There are generally three major IMAPd open-source servers – namely Dovecot, Cyrus and Courier. Herein I sum-up the pros and cons of each of them (based on my experiences and on the things I read):

1. Dovecot

Pros:

Cons:

2. Cyrus

Pros:

  • Supports Sieve language. Sieve can do vacation for example.

Cons:

  • More complicated to set-up and configure.

3. Courier

Pros:

  • Relatively simple to configure.

Cons:

  • Slow with very big IMAP folders, because does not index mails.

XFS is advised to be used for maildir partition FS – easy backup through xfsdump and stability.

Vacation Interface:

  • Gosa2 (for Sieve)
  • timsieved daemon pres nejaky WWW front end (Horde/Ingo nebo SimpleSieve)
