  TCP/IP (UCX) SMTP and a firewall? 
 The Question is:
 
I have a problem whit UCX v 4.0.
 
We have firewall and mail machine whit altavista mail for NT.
Behind those two systems we have 7 alpha system whit VMS (6.0-7.1).
We want to offer vms users internet mail whit vms mail program.
On firewall we defined a rule that only AV mail can send mail in Internet
world.
 
When i send a mail from alpha systems, firewall system block mail becouse
source address are from alpha
machines. I try whit set configuration smtp/options=relay, but I still have
the same problem.

 The Answer is:
 
  Configure a gateway system and route SMTP traffic through it, and enable
  access for this system via the firewall.  Alternatively, enable access
  through the firewall from the OpenVMS Alpha systems -- most sites do not
  restrict SMTP access from within the protected portion of the network.
