Someone's been using my domain to send (tons of!) spam, and so far I've been creating rule after rule using the DreamHost interface.
It's getting kinda silly, though, so I want to create a .procmail filter that kills all email not sent to one of these addresses:
The "*" in the last two is a wildcard, since I use them for spam tracking. For example, I would give foobar.com an address of email@example.com. If I ever get spam to firstname.lastname@example.org, I know where it came from.
I know nothing about .procmail or regular expressions, but I'm happy to have a go. I'm posting this in case someone wouldn't mind giving the newbie some pointers (beyond the KBase article on .procmail, which I've read and kinda understand).
Many thanks for any help!
