[Dovecot] Dovecot failing to start

[dovecot at corwyn.net]

So I rebooted my mail server, and now dovecot fails to start with:
Stopping Dovecot Imap:                                     [FAILED]
Starting Dovecot Imap: Fatal: listen(::, 143) failed: Address already in use
                                                            [FAILED]
