1. an MX record is a DNS entry for a mail server
2. on most systems you can use "telnet xxx.xxx.xxx.xxx 25"
3. next you would have to type "HELO"
4. VRFY or EXPN (username)
end. SMTP 101 :)

you can telnet to a mail server (they usually have exposure to the
internet).
1) lookup the MX record for a domain
2) telnet to that mail server (usually on port 25)
3) do VRFY (username) or EXPN (username)
however, those commands are unavailable sometimes for privacy/security
reasons. or...sometimes you can FINGER an address. from a command line, use
FINGER username@domain.
but that's one way to verify it exists.
you could also send an email to it and have a bot watch for undeliverable
returns. no telling how long that would take to receive though. mail
servers
are configured differently for that both on the outbound and the inbound.

Is there a way to "ping" an email address to verify that the mailbox
exists?
It doesn't neccessarily have to be a CF routine either...
Thanks,
Steve
