    Spoofing incoming email is not blocked in proxmos

    SA score is high so it should be blocked but you have a whitelist item that is allowing this to pass. Be careful what whitelists you add. You should only add the minimal number of whitelists or you will allow spam. Whitelist will allow email bypassing all checks. When action accept that is...

    Feature Request: when quarantine enabled add option to automatically add receivers to mail user welcomelist

    Hello, I don't think this is possible but I think this might make sense. I wish this was a configurable setting once you enable quarantine. For example once the quarantine is enabled and this setting is enabled if a mail user sends a message to some email user this email address should be...

    How prevent the sender the recipients don't exist

    Make sure you restart the server when you make such changes and then test again. I like to test with test email account on gmail, microsoft or yahoo mail and see how things are working by sending a test email to unknown email account for example. Depending on the senders mail configuration this...

    block smtp connection by subject and delete specific messages by console

    I think it's a really bad idea to just delete anything in a way you are doing even if this are just logs. Make sure you have rotation configured correctly here are some threads about this that might be related to your issue...

    Adoption of SpamAssassin improvements?

    I was hoping to see some response from proxmox staff on this issue. We all try to do our best we can do with mail filtering with all limitations in place. Higher pace with implementation of new rulesets of SpamAssassin would be helpful to get better phishing and spam detection. About sharing my...

    Retention in tracking center

    This explains a lot. Will test the daily rotation with 30 rotate value and see how it goes. For now this seems fast but will see when we have more traffic. Now there are holidays so less traffic so faster search is expected.

    Spoofing incoming email is not blocked in proxmos

    I would recommend you post full mail log for your test message (anonymized if you want) from tracking center so we can see more details. For starters you can do the following: Configuration - Mail Proxy - Options - Use SPF - Yes Configuration - Spam Detector - Custom Scores - Create - Name...

    [SOLVED] Can you change the action sender in user (mail@example.com) blocklist?

    Yes this works. Thanks. The priority of your rule is also very important. In my testing if your quarantine priority is higher then block priority then it will still quarantine the message. That is because quarantine action is final. This detail about how blocklist works as you noted was not...

    [SOLVED] Can you change the action sender in user (mail@example.com) blocklist?

    We have implemented the quarantine and it looks OK but I have a question is it possible to change how the sender in user blocklist is executed. Right now I have that any mail over spam score 8 will go to quarantine. If user set's sender on blocklist it will quarantine a message. I would like to...

    Is it possible to use more than one value for Filter in the tracking center?

    For example I would like to use AcceptList & "SA score=10/5" or similar is this possible? I am extremely limited if I have to use just a single value for filtering. If I want to be more specific with filtering I almost always have to use more than one value to do filtering. For example today...

    Retention in tracking center

    Hello @rason thanks for the comment. This makes some sense but I am still unclear what to do. For example I want to have more logs available let's say for start for 16 weeks and searching to be as fast as possible. If I set rotate value to 84 and daily what would that mean? My guess is this...
