You can simplify this. The parenthesized grouping was only necessary when there
was more than one possible string, in my case .com and .net. Since you only
have .com you can remove the (:? and ) and make the regex a little more
efficient:
> header __FROM_THOMAS_1 From =~ /<thomas\.cameron\@camerontech\.com>/i
