Is there some reason the above IP is included in your error report? > Jan 3 15:23:04 alpha.mydomain.com postfix/postscreen[4262]: CONNECT from > [192.168.1.4]:63328 to [192.168.1.7]:25 > Jan 3 15:23:04 alpha.mydomain.com postfix/postscreen[4262]: WHITELISTED > [192.168.1.4]:63328 > Jan 3 15:23:04 alpha.mydomain.com postfix/smtpd[4325]: connect from > unknown[192.168.1.4] > Jan 3 15:23:04 alpha.mydomain.com postfix/smtpd[4325]: disconnect from > unknown[192.168.1.4] A connect/disconnect with no other logs strongly suggests that the receiving postfix is not the problem. Suspects include a configuration error on the sending client, a firewall issue, or a networking problem. Suggestions: - Test the connection from your workstation to postfix with telnet. If that works, it eliminates firewall or networking as possible issues, and points to the sending client software. - Look for errors in the sending software; hopefully it has useful logs. - Record a session with tcpdump to see details of what's happening on the wire. http://www.postfix.org/DEBUG_README.html#sniffer Authentication and/or adding the workstation IP to mynetworks is only useful if postfix is rejecting the mail. This doesn't seem to be the case here since postfix logs all rejections. -- Noel Jones
