Problem
When you address mail to a group (using a Group Internet address) through the Internet, whose group name is the same as a user's last name or first name, a delivery failure report will result, with the following message:
"Maximum forwarding loop count exceeded. Message probably in a forwarding loop. Examine Forwarding Address of intended
recipient in Address Book."
Steps to reproduce:
1. Create a group name, for example, MIA, with the Internet address MIA@tower.sg.ibm.com.
2. Create a user with, for example, first name "Steve" and last name "MIA", with Internet address Smia@lotus.com.
3. Create any other user name to be the member of the MIA group.
4. Send an Internet mail to group MIA@tower.sg.ibm.com (use telnet if you like); you receive a Delivery Failure Report indicating "Maximum forwarding loop count exceeded. Message probably in a forwarding loop. Examine Forwarding Address of intended recipient in Address Book."
Solution
This issue was reported to Quality Engineering.as SPR# PAZR659PFF and has been fixed in Domino 7.0 in the form of a new Notes.ini parameter:
RouterExpansionAllowNonUniqueGroupMatch=1
When the parameter is enabled, it will instruct Router group expansion, during top level group expansion to ignore ambiguous lookup matches that are not groups. This allows group expansion to proceed and will prevent the Routing loop error.
The INI parameter can be implemented by entering the following commands on the Domino server console:
set config RouterExpansionAllowNonUniqueGroupMatch=1restart task Routeror the INI parameter can be added directly into the Domino server Notes.ini and restart the Domino server.
