Issue Dovecot error when starting

[LeighWhiting]

Hi All

I have recently run into an issue where Dovecot failes to start with the below error but when i click the link it just takes me back to the service management page

mailmng-service failed:
Search for related Knowledge Base articles

Any help / advise would be muchly appreciated.

You could try to open a shell and run
# service dovecot start
Then either it displays a specific error message why it does not want to start or it logs one to /var/log/messages or /var/log/maillog.

thank you for the reply, i run service dovecot start and got the below message

Starting Dovecot Imap: Warning: fd limit (ulimit -n) is lower than required under max. load (1024 < 2251), because of default_client_limit
Fatal: Dovecot is already running? Socket already exists: /var/run/dovecot/login/sieve

Yet when i run service dovecot status it says dovecot is stopped

Any suggestions ?
