XIMS: Internet Mail Service Reroutes the Message Even Though the "Do Not Reroute" Option Is Selected (243045)
The information in this article applies to:
- Microsoft Exchange Server 5.5 SP3
This article was previously published under Q243045 SYMPTOMS
When you configure the Microsoft Internet Mail Service for selective IP routing by clicking to select the Host and clients with these IP addresses check box
under Routing Restrictions on the Routing tab of the
Internet Mail Service Properties page,
and add host IP addresses and their subnet mask, the host or client members of this range can route mail, which is the expected behavior. However, if you then
configure the Internet Mail service for no routing by clicking to select the Do not reroute incoming SMTP mail check box on the Routing tab of the Internet Mail Service Properties page,
mail continues to be routed if it is submitted by the same set of host or client members set during the first configuration.
CAUSE
When you switch back to the Do not reroute incoming SMTP mail option, the values of the routing flags and routing restriction IP addresses are not removed from the registry, which causes the behavior described in the "Symptoms" section.
WORKAROUND
To work around this problem:
- In the Exchange Server Administrator program, open the Internet Mail Service Properties page.
- Click the Routing tab, and enable rerouting by clicking to select the Reroute incoming SMTP mail check box.
- Click the Routing Restrictions button, and remove all the IP addresses.
- Click OK, and disable routing again by clicking to select the Do not reroute SMTP mail check box.
- Restart the Internet Mail Service.
After the address is removed from Routing Restrictions, relaying is prohibited if you test by using Telnet as mentioned in the "More Information" section.
STATUSMicrosoft has confirmed that this is a problem in Microsoft Exchange Server Version 5.5 Service Pack 3.
