Next week I get a new list of 500 emails that has never been tested. I would like to do an SMTP handshake(without sending) to verify the domains/addresses that will accept the emails, and remove the addresses that fail. This makes bounce management much cleaner and lowers overhead when you actually send the messages.
This is not actually possible with SMTP. Various MTAs do have the functionality to let you know if they can route to that domain, but that still does not guarentee that the username will be accepted, or that the MX host for that domain is actually accepting mail. -Matt -- Matt Hamilton matth@netsight.co.uk Netsight Internet Solutions, Ltd.
