One of the two reasons i changed my recipient_delimiter parameter to '.'

The other would be that spammers know that anything after a + is usually optional and strip it. Can't do that when the delimiter is a '.'

I do the same thing, for the same reason. I haven't A/B tested both options or anything, but I know I've gotten spam where they stripped the "+" parameter.

I also did that, but I made '_' work, too. Part of me wants to add 'x' as an alternative just for further obfuscation.
