$ tcpip sho ver

   HP TCP/IP Services for OpenVMS Alpha Version V5.6 - ECO 5
   on an AlphaStation XP900 466 MHz running OpenVMS V8.3

$

I simply did :

$ tcpip set service smtp2 -
   /port=2552 -
   /addres=0.0.0.0 -
   /file=TCPIP$SYSTEM:TCPIP$SMTP2_RECV_RUN.COM -
   /flag=listen -
   /limit=5 -
   /log=(file:sys$specific:[tcpip$smtp]TCPIP$smtp2_recv_run.log, all) -
   /process_name="TCPIP$SMTP2" -
   /protocol=TCP -
   /user_name=tcpip$smtp


And then a "$ tcpip enable service smtp2" and I think that was that.

I never opened up port 2552 in my DSL router, just tryed it using
a telnet session to localhost/port=2552. Worked fine so far. There
was no problem sending out mails.
