CF/CFMAIL does not talk to the message recipients email server, it merely
hands off the message to a mail relay (as configured in the CF
Administrator), usually an SMTP server running on either the local machine
or on the local network. At that point it's out of the hands of CF. Once
the message is handed off, most SMTP servers will retry sending the message
periodically over a period of time, generally from one to four days.
The problems lie in the hand-off between CF and this local mail relay. If
the CF server is bogged down, or the mail server is down or bogged, or the
network has problems, all can result in the message going undelivered.
Problem is, you only get one shot.
