    How to train for spam

    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...

    How to train for spam

    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...

    teach spam

    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...

    teach spam

    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...

    teach spam

    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.

    Bays DB connection and sharing

    @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...

    Coexistence with Plesk possible?

    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...

    How to train for spam

    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).

    Relay Blacklist Optimization

    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!

    Relay Blacklist Optimization

    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...

    [TUTORIAL] Installation Tutorials

    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...

    [TUTORIAL] Installation Tutorials

    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...

    Relay Blacklist Optimization

    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...

    Relay Blacklist Optimization

    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.

    How to limit volume email sending via PMG

    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 (Thank u to the team !) but DMARC ?

    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...

    DKIM (Thank u to the team !) but DMARC ?

    For outgoing mails you don’t need to do anything extra, DMARC is a DNS thing, so Proxmox can’t add to the GUI (beside maybe an explanation what to do, but that’s somehow overkill). For inside checking DMARC is somehow implemented in SpamAsssassin by checking for SPF and DKIM. If you also want...

    How to integrate Eset Antivirus with PMG

    That's it, that's what I meant with wrapper. So you may use your own external script or (better and more welcome) contribute your external script code to consider to include with official packages and being able to use ESET out of the box. However, keep in mind as mentioned before, that I...

    DKIM (Thank u to the team !) but DMARC ?

    DKIM is signing messages, SPF is providing a list of "allowed" mail servers to send mails on your domains behalf. DMARC helps you to enforce your settings by getting informed on any misuse and providing guidance on how to handle mails with invalid/missing DKIM signature and violating your SPF...
