Does anyone have actual GOOD results with spam filtering?

[dgeist]

I've been a zimbra user / admin for...well, about as long as zimbra OSS has been available. It's not my business, but I'm in telecom, so it's not a big departure for my knowledgebase.

Through multiple acquisitions, upgrades, migrations to various underlying host OSs, hosted internally, hosted externally, etc. I just want a reliable platform I can manage email for a few personal domains on and have email, calendaring, etc for my family that isn't subject to data harvesting by google.

The problem is that spam controls have pretty much always been mediocre at best. I've done RBLs, baesian, external MTAs, rspamd, and everything in between. I still get lots of spam (mostly in french for some reason) and consistently have problems with people complaining "message x won't go through. your server rejected it". More than a decade later and the anti UBE filtering features still kind of suck, and I'm just tired of dealing with it.

Has anyone actually found a regimen of anti-UBE techniques that works consistently and doesn't have many false positives and which simply puts actual spam in a spam folder for uses (I've yet to see zimbra EVER do that properly on a consistent basis).

Would love something positive, just fed up with the garbage.

Thanks.
Dan

What was wrong with rspamd? Did you try contacting the rspamd mailing list to see if they could help with your problem? The problem with anti-spam systems is they will always need tweaking because the spam ecosphere is always changing and evolving.

Hello,

We are using all instructions from this page and we are very happy with the spam filtering results. We have also hired the invaluement RBL and it works like a charm.

There is a brazilian DNSBL which helps us a lot as well: https://spfbl.net/en/

Thank you for this post, Mark!

Thank you for this link. Although I am comfortable with terminal, it would still be nice to have some anti-spam functionality on the web administration, simple content filter blocking, whitelisting and blacklisting.
