Users can send mail to each other just fine, but when other hosts attempt to send mail they get errors like : ----- Transcript of session follows ----- While connected to foghorn.sfsu.edu [130.212.10.100] (tcp): >-> HELO foghorn <<< 553 foghorn I refuse to talk to myself 554 ...

Sent I'm perplexed as the verbose mail from the remote host says that it sent the mail, but then the HP sends it back with the criptic "i refuse to talk to myself" message. Is the system just schizo, haunted by Rod Serling, or suffering from an inadequate configuration ? Does anyone have any ideas ? I'd certainly appreciate any comments ... e-mail directly to chance@sfsu.edu or post. Thanks in advance ...
