Your friend isn't the only one who's hit this type of problem with MXLogic. It's not sendmail, it's MXLogic. See:
http://www.experts-exchange.com/Networking/Email_Groupware/Exchange_Server/Q_21584053.html for another example of people having issues with MXLogic, and http://www.faqs.org/rfcs/rfc2298.html for the RFC controlling MDNs. The empty envelope from, "<>", in your example transaction *is* correct behaviour for an MDN. If I had to guess the MDN message is getting caught in some kind of anti-relay mechanism at MXLogic. --[Lance] -- Celebrate The Circle http://www.celebratethecircle.org/ Carolina Spirit Quest http://www.carolinaspiritquest.org/ My LiveJournal http://www.livejournal.com/users/labrown/ GPG Fingerprint: 409B A409 A38D 92BF 15D9 6EEE 9A82 F2AC 69AC 07B9 CACert.org Assurer -- TriLUG mailing list : http://www.trilug.org/mailman/listinfo/trilug TriLUG Organizational FAQ : http://trilug.org/faq/ TriLUG Member Services FAQ : http://members.trilug.org/services_faq/
