HCL Notes-Domino mail routing issue, "No names found to send mail to"


There has been an email routing issue for years at a customer which I could not get my head around. Sometimes it seems someone would get the error for no apparent reason.

Today I might have circled in on what the issue is or rather what the bug in Notes/Domino is



I have tested and confirmed it on two different Domino 2 systems.

Scenario:

A = external mail user (MIME/SMTP)
B = internal mail user (Domino mail routing)
C = internal used mail-in database (does NOT have an internet Email address, only Notes/Domino address)

A sends email to B.
B receives the email over SMTP as an MIME email.
B forwards the email to C using Notes address.

The email does NOT get delivered to C.

The Notes client fails to lookup the correct internal Notes address, but instead tries to lookup the internet email address (which does not exist) and fails.
The email then gets stuck in users local Outbox with error "No names found to send mail to" and no recipients in the email.




 
(As a further issue the email in the local Outbox with no recipients will block and delay for further mail to be send from the user, to much annoyance for the user)  

If there are other internal recipients in the email in Sendto, CC  which do have an internet address, they will get the email.
Only the mail-in database with no internet address will NOT get the email.    
 
The correct routing would be to lookup the internal Notes address first for the Mail-in database and send the email to that address, before trying to send to Internet Email address..


(I have created a case at HCL)
