[TUTORIAL] Advancing Proxmox Mail Gateway (especially Spam and Virus Detection)

[killmasta93]

Hi anyone else has been getting this recently?

/etc/cron.hourly/sa-update:
Possible unintended interpolation of @infoadvertising in string at /tmp/.spamassassin4845VvIzhdtmp/70_HS_header.cf, rule HS_HEADER_1771, line 1.
rules: failed to compile Mail::SpamAssassin::Plugin::Check::_head_tests_0_5, skipping:

It looks like heutger is Offline since May 2021.
I hope he is OK, but I am planning to rewrite all 15 pages in one new post, because a lot changed.
Some configurations are EOL and in PMG 7 some features are by default available.

Hello Maxim,
do you have any news on the summary of this forum tread?

"Last seen Apr 30, 2022" - hope you're fine as well.

Any plans for a release of your guide?

I followed this tutorial for very long time and it's working fine.
Until now received this error from sa-update cronjob after updated to PMG 7.3 that shipped along with SpamAssassin 4.0

It seems SA 4.0 doesn't include Hashcash and Maxmind DB Reader modules.
Tried to install Mail/SpamAssassin/Plugin/Hashcash.pm but SA will be downgraded to 3.4 automatically which is not good.

Anyone try to fix this?

I edited `/etc/mail/spamassassin/init.pre` and commented out the Hashcash line. It allows things to work, but probably needs an update that resolves this properly.

 

[dcsapak]

just fyi, the hashcash plugin was deprecated before and is now removed.
quote from the spamassassin 4 release notes:

Removed plugin
--------------

HashCash module, formerly deprecated, has now been removed completely

Hi,
after upgrade to Proxmox MGW 7.3 there is a lot of more Spam. We used sa-update channels like described in this thread.
(for example sa.schaal-it.net).

when I run sa-update --nogpg --channel sa.schaal-it.net -D the debug message is:

Apr 13 15:02:11.273 [3894506] dbg: dns: query failed: 0.0.4.sa.schaal-it.net => NXDOMAIN
Apr 13 15:02:12.964 [3894506] dbg: channel: no updates available, skipping channel


are this rules not compatible with spamassassin 4.0 or might there be a solution to load it with the
new sa-update script ?

Best, Jan
