[Linux-disciples] Port 25 Blocking

[Brian Cooke]

So, today it finally happened.  My DSL provider started blocking port 25 
inbound and outbound unless my ISP is the destination.  Setting up an 
outgoing SMTP server is easy.  I just opened up a new port (say, 250 
instead of 25) and configured my mail client accordingly. 

Anyone have any ideas on getting mail to come in? I was thinking of a 
solution where another mail server (say mail.otherserver.com) would 
accept mail for mail.myserver.com and then transfer to a new 
(non-standard) port where myserver.com is listening for SMTP.   Is such 
a thing possible?  Or maybe a more direct way would be to tell other 
mailservers to just use a nonstandard port when delivering to 
myserver.com.  But I don't know if this is possible, either.

Anyone out there have any suggestions?  I have 3 months before I can get 
off my stupid ISP and find a new one. :)

Thanks,
Brian
