    Default [SOLVED] How to block by IP address

    Hi -

    I'm a new Zimbra administrator.

    I have a user that is getting 3 or 4 virus-infected email messages every day. The messages have differing "From:" in the headers, but they are all from the same IP address. I understand that I can use spamassassin to blacklist senders by email address, but I've not seen anything that tells me I can blacklist by IP address. Is this possible to do? Or, would it be a better solution to just block the address in my router?

    Any advice would be much appreciated.

    Thanks.

    Greg

    I believe you can block by IP, using a filter like this one I found on some obscure forum:

    Code:
    header ANNOYING_SPAMMER Received =~ /255\.255\.255\.255/
    describe ANNOYING_SPAMMER Mark mail from 255.255.255.255 as spam
    score ANNOYING_SPAMMER 5
    However, if you can, you might as well block that IP, and then your mail server won't even have to worry about them.

    Ok, great - thanks much for this information.
