I would be going low-tech and using telnet or netcat or socat to converse directly with your mail server's port 25. Craft the client's side of the conversation in another window and copy-paste lines directly to the SMTP service. This way you can tweak the exact conversation and hopefully trigger the behaviour you are intermittently seeing. ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
