Help with SMTP mail routing through multiple Notes domains...Please?!

We have a mixed environment where we have multiple Notes domains using different versions of Lotus Notes/Domino. Just to set the scenario…

Domain “A” (/ABC)

Lotus Notes R4

Uses an SMTP MTA for all outgoing internet-destined mail

Has worked forever without a hitch

Domain “B” (/XYZ)

Lotus Domino R6.0.3

Internet-destined mail is routed perfectly

Accepts ALL SMTP mail for both Notes domains (company has several Internet domains: “acme.com” used in this example)

Issue

User “Test User/ABC” sends an internet message out. It is routed properly through the MTA

External recipient receives the e-mail fine, and the return address is formatted properly: tuser@acme.com

External recipient replies to the e-mail. It is accepted by Server/XYZ and routed properly over to Server/ABC

User “Test User/ABC” opens the reply fine, and replies to the reply. The reply is then routed BACK through Server/XYZ (follows it’s inbound course) and out to the external recipient.

External recipient receives the e-mail fine, BUT the return address is malformatted: Test_User/ABC%ABC@acme.com

Mail continues to route fine between the two recipients, but we simply cannot produce properly-formatted replies out to the Internet from domain ABC!!

What we have tried sofar (through suggestions in this and other forums)…

We have added the two domains to each other’s “Notes domains and aliases” field in either Global Domain document

As mentioned, the Global Domain doc.'s are setup properly (since outgoing mail is routed fine if not routed between the Notes domains), but just to be thorough:

Use as default Global Domain: Yes

Outbound mail restriction: Unrestricted

Address format: Address only

Internet domain suffix: acme.com (and others)

Internet address lookup: Enabled

Local part formed from: Short name

Notes domains included: None

Notes domain position: Right of ‘@’

Notes domain separator: % - percent sign

The Config document for Server/XYZ works fine (for users sending out mail from the same domain), but we have the following settings (again, to be thorough):

SMTP used when sending messages outside of the local internet domain: Enabled

SMTP allowed within the local internet domain: Disabled

Servers within the local Notes domain are reachable via SMTP over TCPIP: Always

Address lookup: Fullname then Local Part

Exhaustine lookup: Disabled

Relay host for messages leaving the local internet domain: IP address of our relay host

Local Internet domain smart host: n/a

Smart host is used for all local internet domain recipients: Disabled

Host name lookup: Dynamic then local

also (under MIME/Conversion Options/Outbound)…

Lookup Internet address for all Notes addresses when Internet address is not defined in document: Enabled

Perform exhaustive lookups when converting Notes addresses to Internet addresses: Disabled

Is there any way that we can drop the secondary Notes domain from the reply address of outgoing SMTP mail which originates in the primary Notes domain?

Any assistance that y’all may be able to offer would be much appreciated!!

If I can ask… why do you need a separate notes domain? Are they able to be within the same notes name network?

I just want to understand the need for the 2 notes domains because if it was all within one domain the problem would not be as pronounced. Remember that when all servers are in the same notes name network there is not a need for any connection documents for mail routing.

What you have described (2 servers) seems to be a little overkill to have then in their own domain just because they are different versions.

The separate domains are essential, since I am dealing with an organization which runs as separate (semi-autonomous) operations. They are planning a consolidation, but that project won’t be undertaken for some time yet.
