Re: Need to force all SMTP mail through a mail gateway
>>
As far as I can tell, if the substitute domain is set to the same domain name as the domain you're sending to, TCP/IP Services assumes that it's OK to deliver directly to the local host -- ignoring the TCPIP$SMTP_ALTGATE_ALWAYS logical and the SMTP zone setting.
>>
I have the same TCPIP 5.4 version, and the setup is
Alternate gateway: SMTP.MPPMU.MPG.DE
General gateway: SMTP.MPPMU.MPG.DE
Substitute domain: HIDDEN, MPPMU.MPG.DE
Zone: MPPMU.MPG.DE
We have no problem to send to the substitute domain addresses, and it goes through the gateway.
Could it be the HIDDEN tag makes a difference ?
And also I wonder if the zone shouldn't be DOMAIN.COM.AU instead of VMSBOX.DOMAIN.COM.AU,
i.e. one level above the local VMS subdomain ?

gateway. If an alternate gateway is defined and no zone is defined then the local domain (value of the TCPIP$INET_DOMAIN logical) is used as the zone.

Re: Need to force all SMTP mail through a mail gateway
We also lack DNS MX records for our VMS servers and started to get a lot of external recipients rejecting mail generated by the apps we run. Our suggestion to add MX records fell on deaf ears and we didn't get any offers of assistance from our Exchange administrators.
We recommended to our application support folks that they use the TCPIP$SMTP_FROM logical, defined to a legitimate smtp address on our Exchange servrs, as a work around to the problem.

Re: Need to force all SMTP mail through a mail gateway
With this feature, you can use local mail and DECnet mail, but your OpenVMS box otherwise looks like a giant SMTP client as far as your Exchange server is concerned.
Whether the customer might be interested in migrating IP stacks is another discussion. Probably not, but...

Re: Need to force all SMTP mail through a mail gateway
I believe I found the cure for my problem:
$ define/system tcpip$smtp_no_subs_domain_inbound 1
I discovered this logical name on the 3rd or 4th reading of the TCP/IP Services Management Guide.
The description of this logical confirms that if the substitute domain matches the destination domain, mail will be delivered to the local host. Defining the logical name disables this behaviour.
I am waiting for my customer to confirm that their application mail messages are now going to the right place.
Bill and/or Joseph - how did you get the "Hidden" attribute set in your substitute domain setting -- and what does it do? I can't find this documented in the manual or online help.
Thanks,
Jeremy Begg

$ ucx set configuration smtp /substitute_domain=(hidden,name="SECRET")

Re: Need to force all SMTP mail through a mail gateway
It's such a long time I did the setup, so I don't remember the reason.

Re: Need to force all SMTP mail through a mail gateway
As Joseph stated, "It's such a long time I did the setup, so I don't remember the reason."
My intention at the time, was to hide the fact the mail was coming from host.domain.com and substitute the cluster alias, alias.domain.com. This was an attempt to approximate DECnet mail incoming/outgoing alias functionality.
