Marina, he has a public IP on his external interface, why does he need to
forward anything?

I think the key here is 'BT'. FWV, this is BT home service right? If so I
believe they block port 25 traffic into your IP. There are ways of forcing
SMTP to alternate ports (there may be a good google search term there).

However, FWV also suggests they can't telnet to 25 internally, that needs
fixing.
