David,

What system are you going to ping to validate the email address?  Keep in
mind that many (if not most) companies do not point their main domain name
to the same system that handles their email.

I think I understand what you are saying here.  For example we've
purchased a division, mountaincable.com.  (shortly before telephony tanked
:-(  )  Anyways, in the next day or so we will have their isp release
their mx record to us.  These people will have two addresses - a dekko.com
address and a mountaincable.com address.  Still a ping to
mountaincable.com should work, to my best guess.

And since I can't truly verify an email without bounce back then testing
for the domain might be sufficient.

We are dealing primarily with businesses here.  How many businesses will
have a ping fail with TCP3202, ( not TCP3210) yet still receive email at
that domain?  I could be in for a rude shock but I'd like an example.
