Do you know of any online guides that describe "capturing the match" in more detail? I'm finding this concept difficult to grasp.

The .? at the end was used to match from lines that looked like:
From: Jason Burzenski ([EMAIL PROTECTED])
Or
From: Jason Burzenski "[EMAIL PROTECTED]"
While still making sure the TLD part of the domain name was at the end of the line (to prevent things like identifying [EMAIL PROTECTED] due to .fr)
Thanks for all of your help.
