Mail Delivery System report

[Lamaster]

Hello.
I need help with the "Mail Delivery System".
How can I disable the alert that returns to a sender if the destination address does not exist or any different problem?


Thank you
Aleksei

Hello.
Do you mean this log?
/etc/pmg/pmg.conf

no - this is the pmg config file - the logs of (most) Linux system can be accessed through journalctl - see `man journalctl` for details.

<blabla-te-123123123@gmail.com>: host gmail-smtp-in.l.google.com[74.125.133.27] said: 550-5.1.1 The email account that you tried to reach does not exist.

this message says that someone tried sending a mail to <blabla-te-123123123@gmail.com> - but this address does not exist....

Yes, exactly, this address does not exist. I want to disable this alert, is it possible? The sender should not receive this.

In the file /var/lib/pmg/templates/master.cf.in look for the line:

bounce unix - - - - 0 bounce

and change this to:

bounce unix - - - - 0 discard

Personally, i would strongly advise against this, because you should always fix the cause instead of fighting the symptoms, but ultimately it is up to you. Depending on the country, you may also need to know the legal framework, because an email can disappear quietly, the sender thinks it's gone, the server knows it's not and the recipient doesn't know anything about it.
