Dovecot

Overview

Dovecot is email server software. Wikipedia describes it as just a POP3 and IMAP server, but Ubuntu packages it as a "stack" which provides both MTA and MDA functionality.

Helper Binaries

Dovecot includes a number of helper command-line binaries; existing documentation for these is hard to find. Typical locations for these commands are:

• /usr/local/libexec/dovecot/
• /usr/lib/dovecot/

Binaries include:

• /deliver: can be used by Postfix when delivering mail to user mailboxes

Notes

For Ubuntu 10.04 (whatever version of dovecot that corresponds to), some of the settings in dovecot.conf have been pushed out to sub-files. When dovecot is paired with Postfix, the files appear to be:

• auth.d/01-dovecot-postfix.auth
• conf.d/01-dovecot-postfix.conf

If you are experiencing an error where dovecot complains that it can't find cmusieve – like this:

Fatal: Plugin cmusieve not found from directory /usr/lib/dovecot/modules/lda

– then edit the 01-dovecot-postfix.conf file and change "cmusieve" to "sieve". --Woozle 17:41, 23 May 2010 (UTC)
