on hosts that belong to wildcard domains pop3.example.com might
actually resolve to pop3.example.com.[mydomain.com] and give a valid ip
the return code of fetchmail then no longer is 11 (dns failure) but
something else (2 for socket error in our case)
to make sure we always get return code 11 we use the domain name
pop3.example.com. that is not allowed to be resolved to a subdomain.
