[solved] Exim aliases not working

s|mon · Last edited by s|mon on Wed Jun 28, 2023 6:56 am; edited 1 time in total

Hi,

being prompted by ever growing exim mailqueue (triggered by Bug887339) i found out that my exim setup is not working as expect for local delivery and aliases.

Maildelivery to local user 'imap' is working as expected. Handed over to procmail and then showing up in my imap.
Mails to 'root' or 'munin' end up being stuck in exims mailqueue and are not pushed to imap.

Root is on the never to use list (as expected)

Hey
Do you see any errors in "journalctl -fb -u exim" when you restart the service? Are other aliases working?

I am not using systemd, but i don't get any error entries in my logs either. Just the expected stoping/starting exim.
The other aliases in there were not created by me (assuming auto/scripts) and are mostly redirecting to root so not much to test with them.

If i create an alias in /etc/mail/aliases for a non existing user foo and test it it shows

Does /etc/mail/aliases have 644 permissions set?

Is the "system_aliases" section in exim.conf come after "begin routers"

Permissions seem to be ok.
-rw-r--r-- 1 root root 918 Dec 26 17:51 aliases

"system_aliasses" comes after "begin routers" with "dnslookup" being in between both.

ok.. I don't use procmail so I can't say for sure where it's breaking, but I do use exim. If I test an alias, this is the output.

Not sure if procmail is in the loop at all. Even for users which are handled directly without procmail the alias does not apply.
As you see in the differences between our output there is no hint that on my system aliases are picked up.
Maybe i'll make a backup and fiddle around with exim.conf just to test but that is a bit pocking in the dark.
Thanks nevertheless

No worries. I'll let you know if I have any sudden moments of inspiration.

I know this is getting on a bit, but ironically mine have just stopped working

Unfortunately 99% of my email goes to aliases, sooooo... The only thing that I think may have broken it is openssl-3. I got patched from 1.1.1u to 3.0.9 and exim gets rebuilt as a result.
I've downgraded but no change. I even upgraded to 3.1.1-r1 but still nothing. I'm sure I've read a few threads where openssl-3 has caused other damage.

Did you have any luck in the end?

Ah fixed it! The data line from the "system_aliases" block had changed slightly. I checked exim.conf.dist and compared, swapped "data = ${lookup{$local_part_data@$domain}lsearch{/etc/mail/aliases}}" for "data = ${lookup{$local_part}lsearch{/etc/mail/aliases}}" and all working again

Thanks for the update!
Changed the same and now it seems to work as well.
