I wanted to use Dovecot to deal with mailboxes of non-unix users.


* All virtual users/mailboxes are in /home/dovecot/users * Password file for these users is /home/dovecot/passwd (looks just like a htpasswd file)

Making dovecot use these mailboxes

  • auth = default auth_userdb = static uid=500 gid=500 home=/home/dovecot/users/%u auth_passdb = passwd-file /home/dovecot/passwd auth_user = dovecot

By the way, I did not bother making another set of configs to deal with non-virtual users - I use perdition for that in my migration scenario.

Making exim deliver to those virtual users

  • # Transport to send any mail for who a dovecot user exists to the appropriate maildir box # Transports are evaluated in order of configuration, so if you place this # above the local_delivery director this will play nice: # If there is a virtual user in the dovecot dirs it will use that # If not, it will try normal local delivery dovecot_transport:
    • driver = appendfile user = dovecot group = dovecot mode = 0600 directory=/home/dovecot/users/${lc:$local_part}/ maildir_format = true mode_fail_narrower = false envelope_to_add = true return_path_add = true
    # Director to send any mail for who a dovecot user exists to the appropriate maildir box dovecot:
    • driver = smartuser require_files = +/home/dovecot/users/${local_part}/ transport = dovecot_transport

In order to make this work, exim must be able to read the /home/dovecot/users/ directory, otherwise delivery will not work.

Be carefull how you do this - test it with 'exim -bt <address>' for a few different options
