[NTLUG:Discuss] FYI: alternate mail server port

[Jack Snodgrass]

Just set this up on my server....  it doesn't do any good if you don't
have access to your MX
server... 

You can configure postfix on a remote system to send mail for your domain to a 
non-standard smtp port. On the remote mail server, set up a transport
map for your
domain to send to the alternate port ( 1025 in my case ). On the local
system, set up a
master.cnf entry to answer on the alternate port. 

So.. mail for your domain goes to your 'MX' server. Then your MX server has the 
transport map to send to your non-standard port.
