Apparently: (?=...) is true if it matches anywhere after that point, but it is a zero width assertion. So it matches if it occurs in the ".*" prior to the Y bit, and it also matches if it occurs *after* the Y bit. The cool part is it includes a capture, so it will pull out matching text before *or* after the Y bit that can be used in the rest of the expression...
Thank you for unrolling that for me.

I always consider that to be a good thing.
I will have to play with that and see if I can simplify some of my multiple-header-match rules and get from-in-subj to work regardless of the header order.
I'll see if I can't leverage that to compare the Return-Path: and From: headers to see if they are the same. I'd like to add one (or more) point(s) to the spam score if they are different.
I do have some mental logic to compare parent / sibling domains as well as checking the Sender: header.
Thanks!
