>We use Rick Strahl's wwIPStuff for my email operations. The way we handle it is send the email and capture any errors after the fact. We do a very simple validation (like your said only one @ and at least one period) before sending but the primary validation is to do the send and catch the errors. We also have to deal with the undeliverable emails that get by wwIPStuff but don't make it to the address.

Hi Jim,

Thanks, should have known that Rick's IPstuff has the answer. I'll look in there
