I know about modules, I use and prefer them.. read the above reply as to why I'm not using one in this case. As for cut'n'paste, well often modules rely on other modules to run.. which obviously wouldn't work and would easily render a script obnoxiously large. Yes I know that's why modules are written.
Thanks for the hint on the regex in Email::Valid, I'll take a look at it. If I remember, it's quite a monstrous piece, and I don't really know if something like that is necessitated by this project, but I'll look into it.
Hrmm.. and reading your post, I think a better answer to my question may have been, "You know, you can send mail w/out using sendmail. Talk to the SMTP server rather than sendmail", which may indeed be a better way to do it. Good idea, I say. I should have thought of that, but that's why I come here, in case I overlook something or my train of thought is off..
Anyway, thanks..
