FIXED The subject says all. I am on latest ISPconfig 3.29 Im quiet shure it work stiil last week (since years) Using this mail server as mail router works sending via the same mailbox via IMAP works sending via ROUNDCUBE brings SMTP Error (554): Failed to add recipient "[email protected]" (5.7.1 <[email protected]>: Relay access denied). mail.log says <code> root@smtp1:~# tail -f /var/log/mail.log| grep to=\<[email protected]\> Dec 26 18:17:12 smtp1 postfix/smtpd[1247]: NOQUEUE: filter: RCPT from localhost[::1]: <me@mydom>: Sender address triggers FILTER lmtp:[127.0.0.1]:10026; from=<me@zmydom> to=<[email protected]> proto=ESMTP helo=<mymailer> Dec 26 18:17:12 smtp1 postfix/smtpd[1247]: NOQUEUE: filter: RCPT from localhost[::1]: <me@mydom>: Sender address triggers FILTER lmtp:[127.0.0.1]:10024; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mymailer> Dec 26 18:17:12 smtp1 postfix/smtpd[1247]: NOQUEUE: reject: RCPT from localhost[::1]: 554 5.7.1 <[email protected]>: Relay access denied; from=<me@zmdom> to=<[email protected]> proto=ESMTP helo=<mymailer> </code> I did not change anything in ISPconfig otherthan sme DNS entries and I replaced postfix certs. Recieved mails which should only be routet are workin Received mails to the the dovecot mailboxes works. What only not works is sending via roudcube. Need help Rainer
I wondered about localhost[::1]: as I normaly run ipv4 only and found out in main.cf inet_protocols was set ta all. set it back to ipv4 and everything works fine. Rainer
