My question: Anyone have a function to validate e-mails?

Check the PG archives --- this has been discussed before.  IIRC you
can't *really* validate them, short of actually sending mail.

And getting a reply.

But there are partial solutions in the archives.

Even a valid email can be invalid. I periodically receive emails meant for a parent of a ten-year child who has signed up for a kids' site, but who misspelled their parent's email address and put mine in by mistake. I also get emails meant for a contractor in New England whose email address is similar to mine, but has a zero where mine has an "o" (letter "oh"). In both cases the email address is valid in and of itself, but is not valid for the purpose intended.
