This change is intended primarily to satisfy the needs of existing VisNetic MailServer users. Under Deerfield’s previous OEM agreement with IceWarp Technologies, when IceWarp released a new version of IceWarp Mail Server, IceWarp and Deerfield would then develop a separate, rebranded build of VisNetic MailServer. This time differential between releases of IceWarp Mail Server and VisNetic MailServer was originally intended to be a benefit to Deerfield.com customers, as it allowed IceWarp to address any outstanding issues in their IceWarp release before rebranding it VisNetic MailServer. This is no longer an issue due to IceWarp’s improved Beta programs and Quality Assurance testing, which is more inline with Deerfield’s release parameters.
Migrating to IceWarp Mail Server provides customers with direct access to the latest improvements, fixes and features. Additionally, this new partnership allows Deerfield.com to work alongside IceWarp to promote and support IceWarp Mail Server.
