[SOLVED] How to block by IP address
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.
If it's stupid and it works it's not stupid
