Do you think there is any way to stop this type of spam?

https://prnt.sc/ijbwsi

comes from a gmail email, which has several accounts

[email protected]
[email protected]
[email protected]

a list of more than 30 email accounts.

Could I stop it using some filter in the account?

we use Mailscanner

    Take a look at milter-regex.

  • Reporting these spam to Gmail might be the most effective thing to do.

    Your SpamAssassin Size from your screenshot shows "not spam (too large)." Perhaps you can set your Max Spam Check Size higher?

  • We've seen lots of garbage spam come through with lots of "fluff" in the email to bypass content filtering (granted, we use a Barracuda Email Security Gateway) but we were able to solve this by adding a regex filter on the body - <a href=\"http:\/\/\d+.\d+.\d+.\d

    Thanks:

    Is there any way to use a filter that spamassassin score greater than 5, those messages go to a spam folder?

    I think most MTAs like postfix allow you to manually set the threshold spamassassin score and incoming mails will be sorted accordingly.

    As you are using MailScanner, set "Required SpamAssassin Score = 5"
    and "Spam Actions = forward [email protected]"
    in your /etc/MailScanner/MailScanner.conf

    EDIT: IMHO if you don't want to use milter-regex, I would set up "From:[email protected] DISCARD" + "From:[email protected] DISCARD", + etc. in access instead of trying to fix this with Spam Assassin. If you know you don't want any of the mail originating from these addresses why waste the processing time filtering their mail? Just saying....

  • Why not you block emails contain word ventas

    Why not to set various validations? Example:

    1) Validate the mail sending server if it’s generated by gmail server or not and block it at the sending time

    2) other various options of spam score and other filters are available to block the spam email messages

    Any idea how to do it?

    for example as blocking emails that in your message body have

    /unsubscribe
