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

    Thank you @heutger Here is my second day update of Disabling SPF and Graylisting - Well we are processing mails faster, that is for sure - the wait for Graylist is over, but we got a lot more spam today that was failing because of SPF.

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

    TLDR: Thank you for your inputs - I am disabling SPF checks and also grey listing, will keep you updated on what happens next. That was a long read, and I thank you for taking the time out to answer my queries. Reference Bundling Invaluement lists inside Proxmox maybe a good idea, but that will...

    Thank you - I will read up about this - so just to get it correct - all changes to be made for anything are to be in templates, but changes to file /etc/mail/spamassassin/custom.cf are ok?

    Thank you @heutger for your reference of Invaluement - I am right now testing these out. In the meantime, there were a few questions I had from your Advancing setup and thought will ask you here 1. I notice that you are not using Greylisting - in the pmgconfig dump you have shared, your...

    Migrating Bayes Database

    Thank you @heutger - I am still debating if I need the Bayes or not, as I see, that every time I enable Bayes based filtering a lot of spam goes through, this is because users are accepting those emails and not setting up filters. I am still investigating what will be the best manner to go...

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

    Some updates @Stoiko Ivanov I added the links in /usr/share/spamassassin-extras/ into the customs.cf instead of local.cf and now changes from there are also disappearing. This is only happening on the machine where I updated pve-kernel-5.4 (pve-kernel-5.44-2-pve) and not on the machine were...

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

    I have also started noticing a bug - whatever additional rules I add to the file /etc/mail/spamassassin/local.cf keep getting removed, the only rule line that survives this is the KAM.CF but others get removed, not sure how to handle this, maybe @Stoiko Ivanov can give inputs? I am currently on...

    [SOLVED] Changing Return Codes 550 5.7.1 and Others

    Today I noticed that some of the Yahoo.co.in IP's are blacklisted, and while I have set my DNSBL Threshold to 2, and have multiple lists, these IP's appeared everywhere. The Mails were bounced back and the return email to Yahoo said 550: 5.7.1 Service unavailable This to me confuses the sender...

    Thank you @Stoiko Ivanov for moving this - apologies, I made the posting at the wrong place. Thank you for your help. I wanted to check with users such as @heutger or @killmasta93 if they had done this also - to see what their response is. For now I was getting a lot of emails that went through...

    Migrating Bayes Database

    Hi, Slightly off topic, but something that needs to be done with PMG - I have been using EFA for a few years now and have a considerable amount of Bayes Database on the EFA Servers, which may have some false positives, but has a lot of SPAM learning as well as learning of SPAM / HAM that was...

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

    The reason I ask this question is because, when I do spamassassin -D --lint 2>&1 | grep -i --color KAM.cf - I can see that it is loading KAM.cf as shown in dbg: config: using "/usr/share/spamassassin-extra/KAM.cf" for included file but when I do spamassassin -D --lint 2>&1 | grep -i --color...

    Information for a good start with PMG

    Thank you, for you inputs. Actually I have not modified timeout, currently it is set to Default of 10 and I have not changed that. My Only conclusion on saying that could be the reason is, that just before DCC Crashed with the message "dccifd[30843]: write(MTA socket,123): Broken pipe" was a...

    Thank you - Appreciate your Points 1. Big Shoutout to the Proxmox team - I agree that this is the MacOS of what EFA/MailScanner were 2. The Number of 20,000 is the high end number, right now I believe we are doing nearly 2000 Per Server Per Day, but once they go in production - the number may...
