I.e. the domain. Extract the domainname from the given email-address and feed it to either one of these and you'll get a result whether or not the domain has an MX-record. Only thing left is whether or not the user exists on the given mailserver. But for as far as I know you can't automatically check that. -- * R&zE: *************************** ** Renze Munnik ** ** E: renze@datalink.nl ** M: +31 6 218 111 43 ***************************
