Exim, Nobody, bounced emails.

[Adrnalnrsh]

How can I prevent bounced emails from just being sent to Nobody and sitting in the message queue? I would prefer that the emails be bounced back to the domain that it was relayed from. Like some users of a forum that I host setup accounts a while back and the emails are non existing, I would like that forum admin to receive the notifications, not me. However I see that the undeliverable emails are just sitting in my message queue, no notification to the domain owner.

This was happening on my boxes too.

On one of them, i had a copy of exim.conf dated August (so before the upgrades changed things).

I checked the exim.conf used now and exim.conf of the previous version.
Found this on the older file which doesn't exist on the new one (that might explain the behaviour):

######################################################################
#                      REWRITE CONFIGURATION                         #
######################################################################

# There are no rewriting specifications in this default configuration file.

begin rewrite

nobody@lsearch;/etc/localdomains "${if !eq {$header_From:}{}{$header_sender:$header_From:}fail}" Fs
cpanel@lsearch;/etc/localdomains "${if !eq {$header_From:}{}{$header_sender:$header_From:}fail}" Fs

I'm going to try changing the new file adding this part.
Will I have to manually add it or is there a place in the Exim Configurator where we can do this so it doesn't get changed with updates?

Thanks

Along with what JC posted above, the following must be done as well:

You have to add those lines to the rewrite conditions but for it to work you need to modify the following:

At the top of exim.conf you will find:
local_from_check = true
remove it - or comment # it

Then go down to:
#nobody as the sender seems to annoy people
untrusted_set_sender = *

remove it - or comment # it
add this instead:
no_local_from_check

Save restart exim - now it really works :-)

JC sent me that, so I am not taking credit for it, just posting it here so I can point Cpanel staff to the solution.

Ok, I did both of the above and still having the issue.

I cannot run Phpsuexec, and I host a lot of forums, so sending mail as nobody needs to be on, correct?

Ok, update. I disabled the sending mail as nobody option in tweak settings just to see if it would help. And of course it worked and mail is returned to sender. I was also worried if it would stop mail from being sent from some of my forums, and the mail is being delivered!

Yes, you can activate Phpsuexe, but you'll need to change the permission on every single Php file to 755. In addition, Php and other files must be owned by the user, otherwise they won't work. In addition, you need to find good ACLs and RBLs rules for your Exim, to stop dictionary attack, minimize spam, and keep your email server running smoothly.

That's one of the best ways to stop "nobody" from sending out email.

Good luck

I run WHMAP and it doesnt function well under phpsuexec, so I am not using phpsuexec.

As for spam, I just deleted my Exim rule for BFD and setup http://www.configserver.com/free/eximdeny.html
