My jail.conf contains the following.  What I included above was jail.local

[dovecot]

port    = pop3,pop3s,imap,imaps,submission,sieve,25,1025,465,587
logpath = %(dovecot_log)s
backend = %(dovecot_backend)s

[exim]

port   = pop3,pop3s,imap,imaps,submission,sieve,25,1025,465,587
logpath = %(exim_main_log)s


I was also coming to the conclusion that it was time to start again. I'll let you know how I get on
