Cant route SMTP mail between 2 servers in the same domain

Hi Folks:

I really need HELP.

Lets make the task simple.

I have R5 installed in my organization with the following configuration:

Main server on OS/400 - call it A
Additional server on NT4.0 - call it B

A & B are in the same domain. - call it C

I have 12 users registered on A.
And 1 user registered on B.

The server B is connected to the Internet through a ISP.  The ISP uses a proxy for web surfing.
I want my Internet (SMTP) mail to be routed from Server A to server B and finally to the Internet.
I have not registered my company with any ISP, so I do not attempt to download mail, but I believe that one user should be able to send SMTP mail to the Internet

Right now, server A do not route Internet (SMTP) mail to B.

I have run the Mail Trace command from server A to the user in server B, and it was routed successfully.
Any user on A can send mail to the user on B and it gets routed properly ans vice versa.

I have listed in the person doc of user on B that its mail server is B.

I have created a SMTP connection document form A to B:
Connection Type = SMTP
Source server = A
Dest. server = B
Dest. Domain = C
Routing Task = Mail Routing
Route at Once = if 1 msg pending
Routing cost = 1
Router Type = Push Only
The connection schedule is enabled between 8:00 am and 10:00 pm, with an interval of 5 minutes from Mon through Friday.

I have created 2 Foreign SMTP domain docs in the same PAB.  One for A and the other one for B as follows:

For A:
      Allow mail only from domains = *.*
      Internet domain = *.com  (I think this is where I define the domain for outgoing mails, e.g.,,

Should be routed to Internet host = B

For B:
      Allow mail only from domains = (field left blank)
      Internet domain = *.com  (I think this is where I define the domain for outgoing mails, e.g.,,

Should be routed to Internet host = (IP address of the mail server of the ISP).

The minimum I want to achieve for now is that Internet (SMTP) mail getting routed from A to B.  This is very important since both the servers are in the same domain, there should not be any problem regarding this.

Your help is greatly appreciated.

Hi Ideal !

I prepared this document long time back.  Hope this will give you a very good idea on configuring your domino server for smtpmail routing.

There are three steps to be configured for SMTPTA for version 4.6.3.

1.  Connection document.
Type : SMTP
Source Server : Lotus Server Name at your office (full name)
Connected via : Direct connection ( Even though you dialup the vsnl (ISP))
Destination Server : anyhost ( Temporary Server Name )
Destination Domain : SMTPDOMAIN1 ( Again a temporary name that will be linked
later)Relay host : (Your ISP IP address )

2a  Domain DocumentDomain Type : Foreign SMTP DomainInternet Domain :  *.*
Should be routed through domain : SMTPDOMAIN1 ( Linked from connection document in step1)

2b  Domain DocumentDomain Type : Global Domain
Global Domain Name : GlobDom1 (Temporary Variable that will be linked later )
Global Domain Role : SMTP MTA
Internet Domain Suffix : (The part next to the @ in your user name in ISP)

Local part formed from : Short name ( This is the short name field from the
person document make sure you fill this)

3.  Server Document ( Changes to be made)
Routing Tasks : Mail routing, SMTP Mail RoutingIn section SMTP MTA
Global Domain Name :  GlobDom1 ( Linked from Domain Document Step 2a)
Fully qualified internet name : (right part of @ from your ISP name )

NOTE :::  All the unmentioned fields are left to be blank / hold the default
values.  Dont change the default values unless and otherwise mentioned.
