Hitting an address in the From:name

[Olivier Coutu]

I got a spearphishing e-mail the other day that had a From with the 
following form:

From: "Mister President <presid...@company.com>"
        <phish...@freemailer.com>
I attempted to craft a SA rule to catch the "@" in the From:name but I 
was unable to catch anything after the "<"
ex:
From:name =~ /Mister President/        hits
From:name =~ /Mister President \</    does not hit
From:name =~ /\@/                              does not hit
From:name =~ /company/                    does not hit
From =~ /\@.*\@/                                  hits but is inefficient

I believe that SA may be removing the <presid...@company.com> part from 
the From:name, am I correct? Is there any efficient way to detect such 
an occurrence of an "@" in the From:name?
