I though incoming mail was on port 110 (POP3) or IMAP (not sure which
port) SMTP on port 25 is for sending mail

I don't know if it's a DNS issue or not; a mail server is a mail
server, just configure it to listen on a different port and configure
your mail client to do the same. (I think....I could be wrong, though,
anyone can correct me if I am!!)

What a rip-off!!
