Error message intern emails

[Petertjuh360]

Hello,

My clients experience issues with intern mailing. Example: [email protected] mails to [email protected], OR [email protected] forwards to [email protected] and [email protected] forwards to [email protected] forwards to [email protected].

They receive the following error message:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

[email protected]

Action: failed
Final-Recipient: rfc822;[email protected]
Status: 5.0.0

Though the email is delivered, they receive this error message.

I am using Exim 4.86 and have no changes in the exim.conf

Did you check your /var/log/exim/rejectlog for the specific reason for sending this error message?
I'm thinking it might have something to do with local relay.

If you're still using the old exim 2.1.1 conf file, it's probably fixed by adding this line somewhere at the top of the file below the commenting.

no_local_from_check

I always did it like this:

untrusted_set_sender = *
no_local_from_check

But I'm using the newer spamblocker config files nowadays.
