Envelope to 'root@localhost' not accepted

Post by Borisvl »

Hi,
suddenly we have problems to send emails from znuny via O365 emaill account. It works for severel month without any problem.
The communication protocol shows following error messages:

1 Kernel::System::MailQueue It wasn't possible to recover the communication for queued ID "127017". 12.09.2022 18:08:41 (Europe/Berlin)
2 Kernel::System::MailQueue Sending queued message with id '127017'. 12.09.2022 18:08:41 (Europe/Berlin)
3 Kernel::System::Email Trying to send the email using backend 'Kernel::System::Email::SMTPTLS'. 12.09.2022 18:08:41 (Europe/Berlin)
4 Kernel::System::Email::SMTPTLS Received message for sending, validating message contents. 12.09.2022 18:08:41 (Europe/Berlin)
5 Kernel::System::Email::SMTPTLS Sending envelope from (mail from: otrs@ip-92-205-62-221.ip.secureserver.net) to server. 12.09.2022 18:08:41 (Europe/Berlin)
6 Kernel::System::Email::SMTPTLS Sending envelope to (rcpt to: root@localhost) to server. 12.09.2022 18:08:41 (Europe/Berlin)
7 Kernel::System::Email::SMTPTLS Envelope to 'root@localhost' not accepted by the server: 501, 5.1.4 Recipient address reserved by RFC 2606 ! 12.09.2022 18:08:41 (Europe/Berlin)
8 Kernel::System::Email Error sending message using backend 'Kernel::System::Email::SMTPTLS'. 12.09.2022 18:08:41 (Europe/Berlin)
9 Kernel::System::MailQueue Message could not be sent! Error message: Envelope to 'root@localhost' not accepted by the server: 501, 5.1.4 Recipient address reserved by RFC 2606 ! 12.09.2022 18:08:41 (Europe/Berlin)
10 Kernel::System::MailQueue Permanent sending problem or we reached the sending attempt limit. Message will be removed 12.09.2022 18:08:41 (Europe/Berlin)

The problem seems to be the envelope. So we changed the value for Daemon::SchedulerTaskWorker::NotificationRecipientEmail from root@localhost to an valid email address (webmaster@rose.......ch) and we restarted the demaon and also the server.
Nevertheless, we continue to receive the error message "Envelope to 'root@localhost' not accepted by the server: 501, 5.1.4 Recipient address reserved by RFC 2606 !"
We use Ubuntu 20.10 and Znuny 6.3.4.
Any Idea?

Thanks in advance.

Best regards.

Boris

Hi Boris,

your mail server does not accept mails to root@localhost, which is (I think) correct.
Envelope to 'root@localhost' not accepted by the server: 501, 5.1.4 Recipient address reserved by RFC 2606
My guess is: you need to modify your Setting for AdminEmail to a valid mail address.

And also I would suggest to delete the pending mails after that. Otherwise the "old" messages will trigger the error again.

see: bin/otrs.Console.pl Maint::Email::MailQueue
and check the options there.

regards
Johannes
