Eddy, it doesn't read that way to me.  To me it reads that his RaQ is
fine and can use port 25, but he, probably at home, wants to use his RaQ
SMTP server for outgoing email instead of his ISPs mail server for
outgoing email.

It may or may not be in the ISP's TOS; if it's not, then he can
certainly use a different port to reachhis RaQ, if he's willing to face
the consequences.  But of course his ISP could cancel him anyway, and/or
change the TOS.  Changing his ISP may be his best solution, but it's
getting harder and harder to find ISPs that don't block outgoing port
25.  When we did dialup internet access service we blocked it.  The
reason is simple... the anti-spam world is going to hold us liable for
spam originating on our network.  If it doesn't go through our servers
it's not in our logs and it's a lot harder to track (can be done,
through radius logs, but much harder).

We now offer POP before SMTP for clients who want to use our outgoing
server, but we neither recommend it, nor do we try to "fix" it when it
doesn't work, as it's almost certainly an ISP issue.
