If you've recently made the move to MailStore version 9, it's entirely possible you'll be sat there wondering why on earth all of those archiving jobs you had set up can't be modified any more. You'll hopefully be pleased when I tell you it's not a mistake and nothing's gone dramatically wrong, it's just that MailStore are now adopting a new and far more efficient way of automating jobs that no longer needs the old Windows task scheduler method.

As the name suggests, this simple feature allows MDaemon's IMAP server to honour the IMAP compression mode which significantly decreases the amount of data that needs to be transferred during a client to server IMAP session. Typical compression ranges from 50-90% depending on the data being transmitted but the overall increase in performance is undoubtedly beneficial. Unfortunately, not all IMAP clients support IMAP compression so be sure to check your specific client for details. The native Outlook IMAP session doesn't in fact, however ALT-N have addressed this by adding support in the Outlook Connector Client.
