RE: Strange email sending problem

["DeLong, Eric" <EDeLong@xxxxxxxxxxxxxxx>]

Since we have an internal mail server (Exchange), we target that server as
our MAILROUTER, and specify Firewall(*YES).  Our network firewall knows that
the server (Mailrouter) will be handling email, so it's allowed through the
firewall.  When we mistakenly changed FIREWALL to *NO, the as400 tried (with
varying degrees of success) to deliver mail directly to the destination
domain.  

MAILROUTER does not point to the firewall, unless your firewall acts as a
mail proxy....

OK, now this might be promising.  Ours is MAILROUTER(*NONE) FIREWALL(*NO).
The path to the outside world is as follows:

iSeries --> Cisco 2621 Router --> Cisco 506e PIX --> Internet

The IP addresses are:

iSeries is 192.168.0.1

Cisco 2621 router Internal IP 192.168.0.250
                  External IP 192.168.10.2

Cisco 506 PIX     Internal IP 192.168.10.1
                  External IP xxx.xxx.xxx.xxx

Are you saying MAILROUTER should point to 192.168.0.250?  (192.168.0.250 is
already set up as the default route.)  Or is MAILROUTER supposed to point to
the PIX internal IP?  Or should it point to something outside the firewall?

And then FIREWALL should say what?  *YES or *NO?
