IceWarp Mail Server Feature List
Spam Protection
Scalability
Security
Stability
IceWarp Mail Server now features support for Sender Policy Framework (SPF), a new anti spam measure designed to fight email address forgery. SPF verifies the authenticity of the sender's FROM adress by performing a DNS query to verify that the sending server is authorized to send email on behalf of that address. To counter issues with SMTP forwarding IceWarp Mail Server has introduced SRS. SRS forces the rewriting of the MAIL FROM address by the forwarding agent. Learn more. The IceWarp Anti-spam LIVE Service is the first dual protection Anti-spam solution on the market. IceWarp Anti-spam LIVE (Live Identification and Verification Engine) is multi-layer – incorporating the existing power of the Standard IceWarp Anti-spam Engine and the new IceWarp Anti-Spam LIVE Service to bring Spam identification to near-perfect levels. Learn more. DomainKeys technology is a proposed email authentication system for validating and proving authenticity of the domain of an email sender and also the message consistency and completeness. DomainKeys performs functions similar to SPF, because it stops forgery of email sender domains. But it can also ensure that the content of the email was not changed or altered in any way during the transmission. The messages are signed with private keys, the public keys are stored in TXT field of the domain DNS record. Greylisting provides a "temporary reject" of any email not recognized by IceWarp Mail Server. If the email is legitimate, the originating mail server will attempt to resend the message (per RFC) at which time IceWarp Mail Server will accept it. The objective here is that most spammers or automated mailers are not configured to retry messages. Unlike the use of RBLs, which filter on the From email address only, SURBLs allow you to filter and block messages based on spam domains that appear in message body URIs (usually web sites), the message bodies. SpamAssassin combines the most effective anti-spam technologies into one powerful solution that accurately determines what messages are or are not spam. It uses a comprehensive list of rules and checks to score messages based on the likelihood that they are spam. This filtering is completely automated, and spam-scoring thresholds are customizable. It also integrates directly with the Bayesian filters and offers many additional features, such as complete spam message reporting, header reporting and much more. The optional challenge-response mechanism is the last line of defense in anti spam security. It is the most foolproof method to ensure that your organization is spam free. If the SpamAssassin and Bayesian filters cannot definitively prove that a message is or is not spam, a challenge message is sent to the message originator. The originator is presented with an imbedded link in the message. Once they click on this link and enter a password, their message and all of their future messages will be allowed. This mechanism ensures that messages are being sent from a "real" person, and provides the highest level of spam protection. Accurately filter 99% of all html spam messages using these sophisticated rule sets. A common spamming technique is to send messages in all HTML format, which prevents most message body scans from reading data correctly. These filters ensure that these messages are examined and spam is identified. HTML filters are updated with new IceWarp Mail Server software releases to reflect new HTML spam tendencies Razor2 is a distributed, collaborative, spam detection and filtering network. Spam is reported by users worldwide as it is received and a signature of a random part of the message is recorded in the Razor2 database. The signature is regularly re-created using a different random section of the message so spammers can not modify their messages to fool the system. Email from unknown senders which cannot be clearly deemed spam or ham can be quarantined and inspected by the user, spam admin or server administrator, through WebMail or email client via Quarantine Reports or WebAdmin and Windows Administration Console's Spam Queue Manager and the sender Authorized, Message Deleted or Delivered once without authorizing (whitelisting) the sender. This allows for full manual spam processing by a person, semi-automatic by engaging Challenge Response authorization, or user-driven using the mentioned Quarantine Reports. Bayesian filtering statistically calculates the probability that each inbound message is spam. The Bayesian filter updates automatically via a spam database that is uploaded to the server. Bayesian filtering is cutting-edge anti-spam technology capable of eliminating nearly 100% of spam with little to no occurrence of false-positives (legitimate email incorrectly labeled as spam). Because it is measuring probabilities, the Bayesian approach considers all the content in an email, both good and bad. Email containing a high number of bad elements with few good elements achieves a high probability and is automatically deleted, rejected or placed in the recipient's Spam folder. Email containing a high number of good elements with few bad elements is accepted. This ensures that an otherwise innocent email that happens to include the word "buy" is not going to get tagged as spam. IceWarp Mail Server has a very powerful and intuitive email content filtering tool. Filter incoming and outgoing emails based on a number of variables including, subject, sender and/or recipient, key words in the text, and more, through a user-friendly interface. Set the content filter to forward, delete, reject or allow messages. Programs and DLL's can also be executed. You can even create a filter for attachments using layman's logic. IceWarp Mail Server supports several bypass files. If a named file exists with certain content, or if a message contains a recipient or sender listed in the bypass file, the content filters or anti spam filters will be ignored. The file can contain email addresses and domains, IP addresses, masks each per line. All filter files support header, attachment, body, IP, as well as other conditions using RegEx (like 'contains'). Further enable protection by using SPAM email blocker services that incorporate a black list of known spammers, to effectively block the relaying of SPAM through IceWarp Mail Server. White and Black lists allow you to define which email addresses are permitted or denied. Lists can be administered by users or administrators via IceWarp WebMail and addresses can be added via the Challenge-Response Mechanism - e.g., if a message originator verifies himself as a legitimate source he or she can automatically be added to the white list. IceWarp Mail Server supports remote administration options for mail administrators. The Remote GUI is a user-interface that interacts with Mail Server over SSL sockets while providing a familiar interface to enact changes and updates to IceWarp Mail Server from a computer other than the server itself. The Web Administration utility gives an administrator complete control of the mail server through a secure, browser connection. SmartAttach is a revolutionary new feature that allows recipients to download attachments via secure http instead of receiving and processing them by email. This is a logical new technology that saves significant bandwidth and ensures that files are not housed on unsecured recipient mail servers or archives. IceWarp version 10 Webmail is a reimagining of web based email clients. From any browser users may now: send and receive email, schedule appointments and tasks, share contacts, live chat, send SMS messages, and even call contacts and receive calls using IceWarp’s new VoIP capabilities. IceWarp Webmail can now not only be used as a primary email client, it can also provide a hub for all forms of contact and calendaring, from anywhere. IceWarp Mail Server introduces a feature rich File Transfer Protocol (FTP) server. The integrated FTP Server allows users to access their mail folders with FTP Client software. The FTP Server also allows you to schedule live (automatic) mail data backup, transfer files securely, and most importantly ISPs can now offer users email, a web site and remote FTP space, all within IceWarp Mail Server. IceWarp Mail Server includes support for IceWarp GroupWare. GroupWare is collaboration software that integrates directly with IceWarp Mail Server, Outlook 2000/2002/XP/2003/Vista, IceWarp WebMail and any other application via an open API--providing web-based access to shared calendars, appointments and address books. This is an out-of-the box solution that enables easy access to shared address books, appointments, invitations, automated reminders, and more. IceWarp GroupWare is the most comprehensive, cost-effective shared calendaring and address book solution available. ActiveSync provides live synchronization with mobile devices, including most Microsoft mobile devices and Iphones, out of the box without the requirement of client side software. This new feature not only allows for seamless synchronization with mobile devices, but it also makes setup simple and reduces nearly all administrative overhead. Host your own instant messaging server in-house without additional software or installations. Included in IceWarp Mail Server is an Instant Messaging Server that allows you to communicate internally and externally via an encrypted, SSL connection. This method of communication will greatly increase productivity, allowing employees and/or customers to correspond while multitasking, see who is Online/available without leaving your desk, and much more. Also use IM to access pending messages (designated by spam filters) and calendaring information. IceWarp VoIP SIP telephony provides users with the functionality they have become familiar with in services such as Skype, but optimized for business use. IceWarp Mail Server can connect to any ODBC compliant database (e.g. SQL, MySQL, Access). This simplifies setup of user accounts, mailing lists, etc., as existing lists can be imported into IceWarp Mail Server. Support for ODBC connections also allows for centralized management of user data. Instead of creating and maintaining user data in multiple applications, administrators can manage and backup the data in one place, accessing it from IceWarp Mail Server with ease. With Multiple Domain Support, a single IceWarp Mail Server can handle several unique domains (or different addresses). If a company has several identities, all mail can be handled through one server. By reducing the administration burden inherent in running multiple email servers, all email tasks can be made more efficient, and a company can apply consistent routing and filtering rules across all of its accounts. IceWarp Mail Server offers support for POP3, SMTP, IMAP, LDAP, and HTTP. Account holders can check their mail using email software on desktop computers, laptops, cell phones, and PDAs. An email message can be sent to a single address and automatically distributed to several different recipients. Multiple mailing lists, of various sizes, can be created by the administrator. IceWarp Mail Server's List Server allows for the administration of a mailing list via email commands. The List Server also supports moderated lists. A company can take advantage of lists to keep several account holders in contact with one another and quickly contact large groups with critical information. IceWarp Mail Server supports remote administration options for mail administrators. The Remote GUI is a user-interface that interacts with Mail Server over SSL sockets while providing a familiar interface to enact changes and updates to IceWarp Mail Server from a computer other than the server itself. The Web Administration utility gives an administrator complete control of the mail server through a secure, browser connection. IceWarp WebMail is AJAX based for improved usability and performance. Drag & Drop, automatic sign-on, periodical email checking, search, sorting, flagging, image preview and full GroupWare integration. Access email accounts, shared calendars (using IceWarp GroupWare), pending messages (designated by spam filters), and much more via your web browser. IceWarp Mail Server's Remote Account feature makes it possible to collect email messages from any number of POP accounts on multiple servers and deposit them directly into the IceWarp Mail Server user's mailbox. Server subsystem for over-the-air synchronization of mailbox and PIM information (Calendars, Task, Notes, Contacts, Files, Journals) to devices and applications, independently on device type (PC application, PDA, smartphone), platform (Symbian, Palm, Windows Mobile, consumer phones), and carrier protocol (HTTP, OBEX, WSP..). Zero configuration on server side. No client licensing fees. Turn open source email clients into powerful and versatile PIM applications. Unlock GroupWare possibilities of various calendaring applications. IceWarp CalDAV Server is designed for wide compatibility, achieved by combination of WebDAV, GroupDAV and CalDAV protocols and a great deal of technology innovation. Full-featured software gateway to mobile networks allowing users to send and receive SMS messages, send bulk text messages and use SyncML Push technology. By using a special internal protocol, you can bridge email and text messages to send SMS alerts and notifications anywhere where you can send an email. Advanced features include user authentication, gateway load-balancing and support for both locally connected and remote HTTP gateways. Learn more. Zero downtime Migration Tool makes migration from any solution a simple process. Transfers accounts (with passwords!) and mailboxes with no disruption to the traffic, not letting a single message slip through or get delayed. No more export-import hassle. Compatible with any mail server. IceWarp Mail Server eases administration efforts by supporting the import of a pre-existing Windows NT user database. IceWarp Mail Server will use the NT database to create user accounts. API DLL support allows programmers to develop programs and DLL's that can interface with the IceWarp Mail Server directly. This gives programmers the freedom to create programs that allow for direct access to the mail server to manipulate and create domains, users, mailing lists, and more. IceWarp Mail Server can be set up to automatically mail a user-defined message anytime an email is received to the specified users account. Particularly useful for employees who spend a great deal of time out of the office, or during vacations. Passwords are secure, even when logging in across the Internet, because IceWarp Mail Server is able to encrypt this data. VMS supports public IMAP Folders. Public folders are folders available to IMAP users, in addition to their private IMAP folders. When an IMAP user accesses their folder list, they will see both their private and shared folders; mail directories may be shared, while limiting each user to the mail server associated with their individual logon credentials. Route an IMAP message via SMTP to any folder (even shared folders), based on specified criteria. This feature allows administrators to maintain rules settings on the server, as users check email from various clients. Export content filter configurations from Mail Server to Mail Server to eliminate redundancy in recreating complex configurations - great for organizations running multiple mail servers. In business, it is critical to be able to determine when events happen. IceWarp Mail Server performs time synchronization using NTP (network time protocol), the most widely accepted method for maintaining time across a network. NTP is not based on the principle of synchronizing machines with each other, but with having all machines as close as possible to UTC (universal correct time). This feature allows users to retrieve contents of specified directories. For example, you can specify the path to the VMS log directory, send an email to the catalog, and have VMS send the log to you. Control access to public and shared folders using Access Control Lists; specify rights for each mailbox and identifier (user). Support allows IceWarp Mail Server to pass email messages in an encrypted format between servers, and from secure clients (i.e.; any TLS/SSL enabled client; POP3, IMAP, LDAP, etc., like Outlook) to servers. By using these security protocols, a company with multiple offices can create a secure email pipeline with IceWarp Mail Servers at both ends of the connection and with secure clients for employees. Encrypted messages are safe from hackers or information thieves. For email sent to unknown mail servers on the Internet, IceWarp Mail Server will always attempt a secure connection before sending. IceWarp Mail Server is set up to use TLS as its primary encryption method when communicating with another TLS enabled mail server. If TLS is unavailable, IceWarp Mail Server will automatically use SSL. Avast for IceWarp Mail Server places comprehensive email antivirus protection directly on the mail server. By placing antivirus protection on the email gateway, an entire network is protected from inbound email born viruses. This system is monitoring attempts to deliver messages to unknown users, to abuse SMTP commands, to send spam or to relay without authentication and when a certain threshold is reached, automatically closing further sessions for a period of time or permanently blocking connections from such IP addresses. IceWarp Mail Server allows email clients to authenticate before sending and receiving email. By using authentication methods, IceWarp Mail Server can further protect itself from being used as a relay point. Users must identify themselves to the server and be approved to use the mail server. IceWarp Mail Server has a very powerful and intuitive email content filtering tool. Filter incoming and outgoing emails based on a number of variables including, subject, sender and/or recipient, key words in the text, and more, through a user-friendly interface. Set the content filter to forward, delete, reject or allow messages. Programs and DLL's can also be executed. You can even create a filter for attachments using layman's logic. Restrictions can be placed on mailboxes according to overall size, maximum number of megabytes sent per day, even maximum number of messages sent per day. These restrictions help administrators control bandwidth across all accounts. IceWarp Mail Server supports several bypass files. If a named file exists with certain content, or if a message contains a recipient or sender listed in the bypass file, the content filters or anti spam filters will be ignored. The file can contain email addresses and domains, IP addresses, masks each per line. IceWarp Mail Server will recognize and utilize multiple processors installed on the server computer. This results in optimum performance when the server experiences heavy traffic. By taking advantage of all the available processing power, IceWarp Mail Server is able to handle more email faster than its competitors. MDA mode is a separate queue for email processing, recommended for high-traffic servers with extensive filtering, external antivirus engines etc. MDA internal message delivery - bounce backs, server generated messages, account forwards etc. will be placed to incoming queue and processed as incoming emails applying all filters, rules, antispam, antivirus and other. Administrators can configure IceWarp Mail Server to automatically backup critical system information, such as user account data, server configurations, and license data, and will store the backup file separate from the mail server. Should anything happen to IceWarp Mail Server or the computer it is running on, restoration is made easier with the backup file safely stored elsewhere. It is also possible to run a manual backup at any time. IceWarp Mail Server's Real Time Monitoring provides SMTP/POP3/IMAP Statistics on Uptime, Total Connections, Messages Sent/Received, Message Failures due to Viruses, Static Filters and Content Filter Configurations. This information is displayed graphically to administrators, for "at-a-glance" stats on the performance. Active SMTP and POP3 sessions are also displayed, along with session histories. IceWarp Mail Server's watchdog feature ensures that SMTP, POP3, IMAP services (or an ODBC source - Pro version only) are always running. If a service stops for any reason, watchdog will automatically restart it, based on the set time interval indicated by the Administrator. Administrators can also request to be notified when a service is down for more than "x" minutes, and when the server is back online. By automatically monitoring these delivery protocols, IceWarp Mail Server is better equipped to keep itself running smoothly, and delivering email. The Disk Space monitor will track the available hard disk space on the server computer. When the free space reaches a user specified level, the Disk Space Monitor will trigger IceWarp Mail Server to send notification to the server administrator. By actively tracking the disk space, IceWarp Mail Server protects against failure caused by a lack of memory. ATRN allows a user to reliably run a mail server when using a dynamic IP address. When using ATRN, messages are immediately downloaded to the requesting host. DUN support allows IceWarp Mail Server to run even when it is not connected to a permanent Internet connection. Administrators can set connection times and the mail server can automatically trigger the Internet connection, complete its mail tasks, and shut the connection down again. Separate logs can be produced for each individual service in IceWarp Mail Server (including POP3, SMTP, IMAP, and Control and HTTP services). As well, IceWarp Mail Server can produce logs showing activity by users, including the size and number of messages sent and received by each account. |
