Setup a Domain In VisNetic MailServer
VisNetic MailServer supports multiple domains, built around the concepts of a 'primary domain' and one or more secondary domains. There is no particular difference between a primary and a secondary domain. You should realize that domain names and host names are not the same. That means if you have a secondary domain and if you want your users to connect to mail.secondary.com or similar both MX and A DNS records must exist.
From the VisNetic MailServer configuration console:
- Select the Accounts drop down menu and choose New Domain
- Name: This is the name of the domain. It is not an IP address, shortcut or alias but the actual full domain name. Messages can be only delivered to created domains. If a domain does not exist messages will be forwarded outside your server.
- Description: This can be any text used to describe the domain.
- Standard: This specifies a normal domain with users who have separate mailboxes. This is a default.
- Default Alias: Specifies the postmaster aliases. Aliases can be separated by the semi- colon .;. delimiter without spaces. This means you do not need to create those users in the domain as accounts.
- E-Mail: Specifies the actual account for all the postmaster aliases. Multiple accounts can be specified (semicolon delimiter), even remote accounts for different domains. This option must not be empty.
- Info to admin: If an email is sent to an unknown user, the admin (postmaster) for this domain will be notified regardless of whether the mail is rejected or forwarded. Reject Mail: If an email is sent to an unknown user, this option specifies that it should be rejected and returned to the sender. No message will be ever transferred. Forward To: If an email is sent to an unknown user, this will forward it to the specified account. It is quite common to setup a catch all account (for server Domain POP) that will receive all unknown mails. This is how ISP.s offer unlimited email aliases since you can send mail to firstname.lastname@example.org. When using a catch all account it is suggested to switch on the Add X-Envelope-To option for that account.
- Click the Miscellaneous tab
- Domain Virtual IP Binding A domain can be logically bound onto IP's. You can specify multiple IP addresses using a semi-colon. When a user connects to authenticate, VisNetic MailServer will use the specified IP to find the domain. It is not recommended to use this option unless you are familiar with binding to specific IP addresses
- Domain Antispam Filter: In filters you can specify email addresses, domains and IP which defines rules for accepting or rejecting email for this domain. The Global Anti Spam option must be switched on to have this working. Click on the edit button to bring up the text file for editing.
- Domain Admin Account limit This option controls the number of accounts that can be created in a domain by a domain administrator from Web Admin.
- Click Save
If using the Web Admin, from the VisNetic MailServer Web Admin:
- Select the Accounts link
- Click New Domain
- Enter the domain name in the Name field
- Enter any text in the Description field to describe the domain
- If you want the domain bound to a specific IP address, enter the IP address in the IP Address field. If you are not binding to an IP address, leave the field blank. (If the primary domain is bound to an IP it is assumed the other domains are also bound).
- With the drop-down arrow you can select which type of domain it is. Standard specifies a normal domain with users who have separate mailboxes. This is the default.
- Enter the domain's postmaster alias in the Default Alias field. Aliases can be separated by a semi-colon ';' delimiter without spaces
- Enter the actual account for all the postmaster aliases in the E-Mail field. This option must not be empty.
- Click Add Domain
