If I try connecting to pop.threeofus.com on TCP port 110, I get the "connected" message from Telnet, but a few seconds later your end disconnects. That usually means TCP-wrappers is hosed, or DNS is hosed, or both. Or are you using IP address restrictions deliberately? If I try connecting to mail.threeofus.com on TCP port 25, the SMTP banner starts out as "220 localhost.localdomain ESMTP ...". Your system appears to think it's canonical name is "localhost.localdomain". That may be a problem. The MX record for <threeofus.com> points to <mail.threeofus.com>, which is a CNAME record. MX records should only point to canonical names. That is likely not causing many problems, but should be fixed eventually.
