I’m having trouble with a single user for who mail is rejected on one of two servers (but not on the other), but I can’t see why.
User ‘gerben’ works fine. User ‘vanroodewierda’ is rejected: Feb 18 12:18:43 snape smtp/smtpd[15128]: connect from ms11p00im-qufo17282001.me.com[17.58.38.57] Feb 18 12:18:43 snape smtp/smtpd[15127]: connect from ms11p00im-qufo17282001.me.com[17.58.38.57] Feb 18 12:18:44 snape smtp/smtpd[15128]: NOQUEUE: reject: RCPT from ms11p00im-qufo17282001.me.com[17.58.38.57]: 550 5.1.1 <vanroodewie...@rna.nl>: Recipient address rejected: User unknown; from=<gerben.wie...@icloud.com> to=<vanroodewie...@rna.nl> proto=ESMTP helo=<ms11p00im-qufo17282001.me.com> Feb 18 12:18:44 snape smtp/smtpd[15127]: 0C666492E2: client=ms11p00im-qufo17282001.me.com[17.58.38.57] Feb 18 12:18:44 snape postfix/cleanup[15131]: 0C666492E2: message-id=<b9b6b646-a193-4a8b-800f-c7803b357...@icloud.com> Feb 18 12:18:44 snape smtp/smtpd[15128]: disconnect from ms11p00im-qufo17282001.me.com[17.58.38.57] ehlo=2 starttls=1 mail=1 rcpt=0/1 data=0/1 rset=1 quit=1 commands=6/8 Feb 18 12:18:47 snape postfix/qmgr[131]: 0C666492E2: from=<gerben.wie...@icloud.com>, size=2013, nrcpt=1 (queue active) Feb 18 12:18:47 snape smtp/smtpd[15127]: disconnect from ms11p00im-qufo17282001.me.com[17.58.38.57] ehlo=2 starttls=1 mail=1 rcpt=1 data=1 quit=1 commands=7 Feb 18 12:18:47 snape postfix/local[15132]: 0C666492E2: passing <ger...@rna.nl> to transport=lmtp Feb 18 12:18:47 snape postfix/lmtp[15133]: 0C666492E2: to=<ger...@rna.nl>, relay=snape.rna.nl[private/dovecot-lmtp], delay=3, delays=3/0/0.02/0.02, dsn=2.0.0, status=sent (250 2.0.0 <ger...@rna.nl> 0OViASfC8GMeOwAAy+4yzw Saved) Feb 18 12:18:47 snape postfix/qmgr[131]: 0C666492E2: removed But both are available in dovecot: / # doveadm user gerben field value uid 214 gid 8 home /var/mail/nl.rna.mail/users/gerben mail maildir:/var/mail/nl.rna.mail/users/gerben / # doveadm user vanroodewierda field value uid 214 gid 8 home /var/mail/nl.rna.mail/users/vanroodewierda mail maildir:/var/mail/nl.rna.mail/users/vanroodewierda I’m kind of lost, how do I find out why I’m getting ‘User unknown’ here from postfix? Is there a way to run a test with more verbose output that I cans why one works and another not?
