Frederic,

thanks for your suggestion. /etc/hosts was indeed defaulting to localhost
and localhost.localdomain as the only values for 127.0.0.1

Changing it as you suggest _does_ (will it impact other services???):

     127.0.0.1 machinename.domain.dom localhost localhost.localdomain

causes "hostname" to return "machinename.domain.dom". It is not enough,
however, to make fetchmail helo with that value, or so I understand:

having smtpaddress set or not in the fetchmailrc file doesn't change
anything. What now?

Thanks,
