Regex Expression Help - ORF Forums

I've got some spam that is coming through that I'm seeking some help on how to come up with a regex expression that will catch it. They are plain text emails and the only common denominator between all the emails is they have a "header" if you will at the top of the email. I've listed them below. Any suggestions on how to setup the regex expression would be greatly appreciated.

Krisztián,

Thanks for the suggestion! I appreciate it. I'm going to try turning on graylisting for a few days before trying to implement the expression above.

Thanks!
Josh

The graylisting didn't work, but as I continued to get spammed there were some patterns in the servers/IP's and I just blacklisted them.

If it continues, I'll try giving the regex expression a shot.

Thanks again.
Josh

Can you recommend any regex tutorials or builders that are very basic? I've got another rash of spam today and feel I could implement some keyword blacklists with regex expressions, but for whatever reason my brain just doesn't seem to grasp regex expressions very well.

Thanks
Josh

Thanks for the suggestions Peter, I'll check them out.
