I personally use a different, but still perfectly compliant suffix character. So just simplistic +suffix filtering isn’t complete. I’ve also considered using a double suffix and having the first one be required, so if someone cut off all suffixes it would go into junk anyway.

I have a script which generates random addresses for each site, with a database to lookup what E-mail belongs to each. No regexing away that!
