A little stuck here. Tried sending a mail to test the setup, and I keeps getting bounces with 5.1.1 Unknown User. Already checked the MySQL connection and also logged the query and everything seems to be fine with the database. Here's my log entry: Code: Jun 11 13:29:10 ivory postfix/smtpd[6539]: connect from unknown[127.0.0.1] Jun 11 13:29:10 ivory postfix/trivial-rewrite[6527]: warning: do not list domain haloandwingsstudio.com in BOTH mydestination and virtual_mailbox_domains Jun 11 18:29:10 ivory postfix/smtpd[6539]: 8EA8C14EACFE: client=unknown[127.0.0.1] Jun 11 13:29:10 ivory postfix/cleanup[6532]: 8EA8C14EACFE: message-id=<[email protected]> Jun 11 13:29:10 ivory postfix/qmgr[6297]: 8EA8C14EACFE: from=<[email protected]>, size=2594, nrcpt=1 (queue active) Jun 11 18:29:10 ivory postfix/smtpd[6539]: disconnect from unknown[127.0.0.1] Jun 11 13:29:10 ivory postfix/trivial-rewrite[6527]: warning: do not list domain haloandwingsstudio.com in BOTH mydestination and virtual_mailbox_domains Jun 11 13:29:10 ivory amavis[5538]: (05538-05) Passed CLEAN, [64.233.184.227] [64.233.184.227] <[email protected]> -> <[email protected]>, Message-ID: <[email protected]>, mail_id: ddSRgo+pvr7C, Hits: 0.001, size: 2096, queued_as: 8EA8C14EACFE, 1618 ms $ Jun 11 13:29:10 ivory postfix/smtp[6533]: CD47C14EACBF: to=<[email protected]>, relay=127.0.0.1[127.0.0.1]:10024, delay=1.9, delays=0.29/0.02/0.01/1.6, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as 8EA8C14EACFE) Jun 11 13:29:10 ivory postfix/qmgr[6297]: CD47C14EACBF: removed Jun 11 13:29:10 ivory postfix/local[6540]: 8EA8C14EACFE: to=<[email protected]>, relay=local, delay=0.12, delays=0.03/0.07/0/0.03, dsn=5.1.1, status=bounced (unknown user: "karl.tobias") Jun 11 13:29:10 ivory postfix/cleanup[6532]: ABA8B14EACFF: message-id=<[email protected]> Jun 11 13:29:10 ivory postfix/qmgr[6297]: ABA8B14EACFF: from=<>, size=4592, nrcpt=1 (queue active) Jun 11 13:29:10 ivory postfix/bounce[6541]: 8EA8C14EACFE: sender non-delivery notification: ABA8B14EACFF Jun 11 13:29:10 ivory postfix/qmgr[6297]: 8EA8C14EACFE: removed Jun 11 13:29:11 ivory postfix/smtp[6542]: ABA8B14EACFF: to=<[email protected]>, relay=gmail-smtp-in.l.google.com[64.233.167.114]:25, delay=1.1, delays=0.02/0.03/0.38/0.7, dsn=2.0.0, status=sent (250 2.0.0 OK 1213208951 w43si257375pyg.14) Jun 11 13:29:11 ivory postfix/qmgr[6297]: ABA8B14EACFF: removed Jun 11 13:29:39 ivory postfix/smtpd[6524]: disconnect from wr-out-0506.google.com[64.233.184.227] Any clue?
