Maybe you could post to the developers mailing list to get integrated with PMG directly.

Makes sense, however, I don't prefer to use a quarantine for our company or finally in productive environments as most like us are working in a timely urgent business, so I can't always let my stuff recheck quarantine on mails, which may got caught there. It's much easier, just to deliver mails...

Das Resultat würde mich auch interessieren. Ich hatte dieses Phänomen schon mal mit der damaligen ESVA, jedoch mit dem PMG nicht mehr. Damals war es auch der SpamAssassin der die Zeilenlängen anders gewählt hatte und dadurch die Signaturen ungültig gemacht hatte (überprüft durch eine...

That's getting the quarantine per absurdum. The idea of the quarantine is not to deliver potential spam and have a single point to check potential spam and decide if you want to release it (if it isn't spam) or delete it (if it is spam). But now you need to release spam just for moving it into...

That’s exactly the issue: As PMG doesn’t see itself as final destination (e.g. as archiving server or mail server like Kollab) there needs to be an integration with the final server. Beside fetching each spam box from IMAP servers (which would only train spam), having a centralized mailbox for...

That's it. It's a hard and time consuming job (without mail server behind and scripting to use it as a "learn base", e.g. if you manually import all spam messages on PMG and train them there, but it's exactly my experience as well). This are the values of my private installation, I trained...

So finally bayes scores are working well for you as for me. For sure, there are no much data about that, as PMG in its usual deployment (of people, who won't ever enter the shell and do any adjustments and also then won't train the bayes database and as mentioned, it takes a long long time to...

Would be great to see the results. On my private PMG installation, I have bayes trained and the filter works much better. I was able to reduce the milter-reject (and in future before-queue) reject at a spam level of 5 without any false-positives. So yes, I believe, a well trained bayes filter...

Or you use sa-learn via command line on PMG to train mail as spam or ham to improve the bayes filter.

@Stoiko Ivanov Would be great to sync Bayes DB as well. For sure, it's currently hard to train via PMG. Quarantine does not provide to learn the still one PMG placed spam as spam or ham as ham to PMG and once the mail is delivered to the destination server it needs coding to get the message...

You will get dependency errors and loose Plesk support by installing PMG on the Plesk server, so I don't recommend to do so. Maybe you could try to run PMG via Docker on the Plesk server, but that's as well strongly not recommended. You should install two separate hosts or try to migrate the...

Great job. That looks fine. However, using Sieve to invoke sa-learn on PMG would be my goal or much better seeing Proxmox team integrating PMG with archiving and mail server (e.g. something like SoGo or Kollab).

One more update: All our out again. Scientficspam has significant false-positives, Beetjevreemd has a 3:1 ratio of false-positives:hits, so it's out as well. EDIT: for me, I only test for myself, so please do your own tests!

My plan is to update my thread soon and also move the content to Github (to keep it easier to maintain for me and the users). I also plan to write some more about my security optimization trials with SPF, DKIM, DMARC, TLS 1.3, DANE etc. Currently I'm very spare of time, especially now at Corona...

I believe, the answer shouldn't read such way. However, in the beginning of PMG getting Open Source, there were really stupid questions in the forum, wrong postings or questions in other language without any glue, which language it is and why they don't use e.g. Google Translator (or I prefer...

I don't know, why this escalated as such much. And I also don't understand, why this topic arises again, although it has already been cooled down. From my point of view, the question was, if someone can contribute tutorials in Spanish. However, I also don't understand, why anyone from the...

No, as written, this post is only to document, which blacklists I tested. It’s for others as well but mostly for me to be able to check, if I already tested a blacklist or not as there are so many. The final set is somehow on my Advancing PMG Thread, somehow because the last two lists are xxxed...

Update: I got contact with the operator of dnsbl.beetjevreemd.nl and it seems only to be accessible via IPv6. black.dnsbl.brukalai.lt and light.dnsbl.brukalai.lt are both producing too much false positives, they are both out. New one to test is bl.scientificspam.net and rhsbl.scientificspam.net.

As written, provide a use case, open a feature request bug in the bug tracker and maybe it will be added in future. However, PMG isn't meant (currently, I would also prefer something different to improve the product, e.g. adding archive functionality, adding mail server functionality, adding...

DKIM is broken by design, SPF as well. SRS is not always implemented, ARC (to fix problems with DMARC) is much less implemented. I can send mails to Google Mail Abuse address about all the well SPF approved and DKIM signed DMARC valid spam I get from them without using SPF and DKIM or DMARC on...
