Support for Spamhaus DQS

Hi,

PMG follows SpamAssassin upstream for the greatest part - so should the SH plugin get included in upstream it would be provided with PMG with the next SA release.

For now you can easily integrate a third-party plugin by enabling and handling the SpamAssassin configuration via PMGs templateing system:
https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#pmgconfig_template_engine

As far as I can see you need to register for the service - so this part will (most likely) remain out of PMG - and you'd need to .

What kind of integration would you have in mind? (enabling the plugin does not work if you don't have a key for the service)

Do you have any concrete numbers regarding the effectiveness or any pattern of spam, which DQS helps catch?

(This would help us to get a more complete picture regarding the effectivness in the future)

I hope this helps

I was thinking of a way to enable the plugin and set the key directly from the web UI.
I know, I'm lazy :-)
Installing it from the command line it's not a bit deal (I've just done it in my test proxmox machine), but being able to manage most of the system from a unified UI is one the strengths of PMG

In my (limited) experience I played a bit with SA bayesian filters during the years, but I was not able to achieve fully satisfactory results (and they seemed quite slow to catch new "waves" of spamming).
I'm sure it's was fault, but with this plugin I immediately saw a decrease of about 80% of the total spam in my customers' inbox.

Thanks for your reply,
Emanuele

Hello,

based on the VirusBulletin survey we participate in, DQS will increase spam detection by 40-50% compared to using the public mirrors with no plugin.

You'll get another bonus boost if you use the HBL component
 
have you configured any DNSBL for the Mail Proxy?
(GUI->Configuration->Mail Proxy->Options)
 
Oh yeah... and adding spamassassin-dqs to the pmg repo would be a nice start
 
Hi,

Any news about this?
I have been playing around with pmg the last days and could not get the default RBL checks working correctly (even after setting up a local unbound resolver).

I just installed this plugin, and on the first try it immediately catches all the test spam messages from Spamhaus.

Does this survive updates? I have 'Use RBL checks' on under 'Configuration' -> 'Spam Detector' -> 'Options', so the HashBL plugin in '/etc/mail/spamassassin/v342.pre' is enabled according to the template.

There are two files copied to '/etc/mail/spamassassin' and after doing a 'pmgconfig sync --restart 1' everything is still there, so I assume it survives an update?

Hello Nickske00,

I have the same question as you. The plugin installation survive to an update?

Maybe, after one year, you probably ran an update on your PMG. What about the plugin? Still functional or death?

Thank you in advance for sharing your experience.

In my case, I didn't have to modify any PMG config files on install, so it should survive PMG updates (and in fact has for almost a year). If you followed standard install, you should be in the same boat.

If you did modify a config file (v342.pre? should not be needed if "Use RBL checks" is enabled in the GUI), use a template (see post #2 by Stoiko) instead and you should be good on future updates.

If you modified SA scores, like me, make sure you add them to your own file or custom.cf, not one of the files managed by the plugin (sh.cf and sh_scores.cf), since this may be overwritten on a future DQS plugin update (would mean an update to the plugin is available and you manually update it).
