Good day!
Proxmox - Spam detector - Custom Scores. The correlation rules do not work. How to fix this?

Hello,

Just to be sure to not miss the obvious here: you did indeed apply the changes using the Apply button in the "diff" panel at the bottom of the Custom Scores tab?

Yes, sure. and tried to restart various services, and tried to reboot the host, but for some reason the correlation does not apply

* how does the file `/etc/mail/spamassassin/pmg-scores.cf` look on your system?
* what's the output of `spamassassin -Dall --lint 2>&1 |grep pmg-scores` ?

Good day, Stoiko

spamassassin -Dall --lint 2>&1 |grep pmg-scores:

but the pmg-scores.cf file is empty. What needs to be added to this file?

this is the file where the custom scores are written once you apply the changes you did in the GUI as @t.lamprecht pointed out.
try changing a score (or adding a 0 score for a bogus rule) and clicking Apply again) - check the journal and /var/log/pmgproxy/pmgproxy.log to make sure there is no error in that part.

As I said, I save the changes in the GUI, but for some reason they are not made to /etc/mail/spamassassin/pmg-scores.cf

This call should apply the custom scores (and the diff should then vanish from the bottom of the page...)
Tested this here - and it works reliably

after applying the scores - what's the content (if the file exist) of:
* /var/cache/pmg-scores.cf
* /etc/mail/spamassassin/pmg-scores.cf
also - do you see any issues in the system-journal when you apply the scores?

using the example of adding a MIXED_ES rule with a score of 1

1.created a rule

the contents of the /var/cache/pmg-scores.cf file changes to:
1727777277676.png

2. In the GUI I execute apply
1727777349300.png

the /var/cache/pmg-scores.cf file is not cleared and the /etc/mail/spamassassin/pmg-scores.cf file remains unchanged

any messages in the system journal? (see `man journalctl`)
 
please post text as text (in a code block) instead of screenshots

else - please post the output of `mount` and `ls -la /var/cache`, and `pmgversion -v` (as text in code blocks)

how was the PMG setup? (install from ISO, is it a container running on PVE, was it installed on top of a Debian GNU/Linux installation?)

Thanks for the information - I think I found the issue - your PMG has /var on a separate filesystem - and the moving of the file does currently not work across filesystem boundaries - I prepared a patch to address this:
https://lore.proxmox.com/pmg-devel/20241002172238.20947-1-s.ivanov@proxmox.com/T/#u

once this or an improved version has been applied and released applying the custom scores will also work for your installation!

Thanks for the report!!
