I had a similar problem at some point. I fixed it by removing an idiotic 
alias in my /etc/hosts file. Some dingbat had aliased the server's FQDN 
to localhost. Maybe it's the other way 'round in your case.

Not optimistic, just the first thing that sprang to mind. (Pessimistic 
because I'd expect aliasing localhost to something other than 127.0.0.1 
would break a lot more than just dovecot.)
