Subj : Postfix and mail redirection?

Anyone here using Postfix to deliver mail to their BBS? This is my first 
time playing with Postfix, and my last experience with SMTP mailers was 
Sendmail back in 2004.

My ISP blocks port 25. I use a mail redirection service that acts as my 
primary MX and receives email from the world on port 25. I'd like to 
recreate that service on my VPS, outside.realitycheckbbs.org to act as 
primary MX for realitycheckBBS.org and connect to my BBS on an altenate port 
(I'm using 940) to transfer mail onto the BBS.

I added a transport_map entry referencing a file called transport:

[transport]
realitycheckBBS                   smtp:realitycheckbbs.org:940

then, ran postmap /etc/postfix/transport.

I've added a line for 940 in master.cf.

inet n  -  y  -  -  smtpd

I've got my MX record pointing to outside.realitycheckbbs.org now, and when 
I try testing, it looks like postfix is trying to deliver to itself on port 
940, so it looks like it's reading my transport_map. Any suggestions on 
where to look next?
