In this example, I send from [email protected] to [email protected]. Here's the maillog: Code: Oct 30 18:13:17 www postfix/cleanup[29093]: 86245A68275: message-id=<[email protected].***> Oct 30 18:13:17 www postfix/qmgr[29048]: 86245A68275: from=<[email protected]>, size=1657, nrcpt=1 (queue active) Oct 30 18:13:17 www postfix/local[29094]: 8002CA68257: to=<[email protected]>, orig_to=<[email protected]>, relay=local, delay=0, status=sent (forwarded as 86245A68275) Oct 30 18:13:17 www postfix/qmgr[29048]: 8002CA68257: removed Oct 30 18:13:17 www postfix/local[29095]: 86245A68275: to=<[email protected]>, orig_to=<[email protected]>, relay=local, delay=0, status=bounced (mail forwarding loop for [email protected]) Oct 30 18:13:17 www postfix/cleanup[29093]: 90EA0A6827B: message-id=<[email protected]> Oct 30 18:13:17 www postfix/qmgr[29048]: 90EA0A6827B: from=<>, size=3593, nrcpt=1 (queue active) Oct 30 18:13:17 www postfix/qmgr[29048]: 86245A68275: removed Oct 30 18:13:17 www postfix/smtp[29050]: certificate verification failed for konsept-it.no: num=20:unable to get local issuer certificate Oct 30 18:13:17 www postfix/smtp[29050]: certificate verification failed for konsept-it.no: num=27:certificate not trusted Oct 30 18:13:17 www postfix/smtp[29050]: certificate verification failed for konsept-it.no: num=21:unable to verify the first certificate Oct 30 18:13:17 www postfix/smtp[29050]: Server certificate could not be verified Oct 30 18:13:17 www postfix/smtp[29050]: 90EA0A6827B: to=<[email protected]>, relay=konsept-it.no[91.189.123.***], delay=0, status=sent (250 2.0.0 Ok: queued as B1C9382802D) Oct 30 18:13:17 www postfix/qmgr[29048]: 90EA0A6827B: removed Here's the reply I get from the server: Code: Reporting-MTA: dns; www.enjoydancing.com X-Postfix-Queue-ID: 86245A68275 X-Postfix-Sender: rfc822; [email protected] Arrival-Date: Tue, 30 Oct 2007 18:13:17 +0100 (CET) Final-Recipient: rfc822; [email protected] Original-Recipient: rfc822; [email protected] Action: failed Status: 5.0.0 Diagnostic-Code: X-Postfix; mail forwarding loop for [email protected]
