Yeah, I thought about combining the two scripts, but I could see how having emailverify.pl as a stand alone might be useful. Also, though it's not an excuse, I pulled e-mail addresses from data files totalling close to a gig, possibly more, of raw data. It was only after I collected the data that I saw how much extra sorting I was going to need to do.

Thanks for the cleanup, though. I don't hardly get to do enough PERL these days, so my code is even sloppier than it used to be!
