One way is to separate the mailbox and domain names from each email address.
Then do a DNS query to find the MX record(s) specifying the IP address(es)
for the domain, then connect to the SMTP server(s) at the IP address and
issue a VRFY command specifying the mailbox name. You can use the TIdSMTP
and TIdDNSResolver components for that.
