What’s New in Version 10.6

Mail Service in Mac OS X Server 10.6 includes many internal changes to enhance performance and scalability. Fundamental among these changes is the move from Cyrus to Dovecot with Dovecot now handling IMAP and POP Mail services. Among the reasons Dovecot has been integrated into the Mac OS X Server Mail Services are the following:

  • It integrates better with other Mail services tools by using industry-standard mbox and maildir mailbox formats

  • Process usages is much lower as it does not spawn a new process for each connection

  • Reliability of the overall Mail services are enhanced with Dovecot’s self-optimizing and self-healing indexes

  • Expandability is enhanced with support for NFS and clustered file systems (like Xsan)

For more information on Dovecot, seeDovecot.

In addition to the move from Cyrus to Dovecot, the following are other new attributes of Mail Services for Mac OS X Server 10.6:

  • All Mail Services are 64-bit native.

  • Vacation messages and server-side mail rules are available through Sieve scripting.

  • Notification Services for use with iPhones and other clients in enterprise environments.

  • Proxy integration.

  • Virtual Hosts are now handled by Postfix instead of the local delivery agent.
