Put both computer's details in both computer's hosts file, using the same scheme as the localhost lines (numerical IP address, hostname, alternative host names). e.g. 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.0.1 Teucidide 192.168.0.2 homere (Using YOUR actual IP address, not just copying the example above) That'll help with various networking things between your two computers. I don't believe that sendmail will do anything beyond send mail to itself unless you customise its configuration, and open ports through your firewalls. If you don't need to send mail between your computers, then you don't need to do anything about that. In a prior message you mentioned this: > Jul 28 12:07:57 homere sendmail[76758]: My unqualified host name > (homere) unknown; sleeping for retry It used to be that sendmail required a fully qualified domain name, that is a hostname and domain name combination with at least one dot somewhere in the middle. I didn't think that's still the case. I'm wondering if it's misusing the term "unqualified hostname" (hostname is not the same thing as a full domain name), but if it's the case it still needs a FQDN, then add such info to your hosts file. e.g. Expand on my previous example something like this: 192.168.0.1 Teucidide Teucidide.localdomain 192.168.0.2 homere homere.localdomain -- NB: All unexpected mail to my mailbox is automatically deleted.
