Thanks for the reply Ed. The messages (in question) are inbound from the internet, not NDRs. They seem to be taking 8-9 hours to get out of the queue. Once they do they are delivered.
I removed the SPAM filter from the loop for 90 minutes. It had no effect, so now it looks like it is something to do with the front-end server. As to the placement of the SPAM filter, I am not sure. This is an inherited design. But it seems reasonable. It is configured as a transparent bridge and is only filtering SMTP incoming for SPAM. The Front-End server is inside a DMZ. The Webshield SPAM filter is inside the network.

Why is the antispam server between the front-end and back-end? It should be the first server inbound from the Internet.

We have two Exchange Servers � in a front-end / back-end configuration. For the last day and a half, the SMTP Queue from the front-end server to the back-end server has been processing mail extremely slowly. 8 hours is not atypical for a piece of mail to go although some mail goes through relatively �quickly� � ((as in 20 minutes). The queues have a lot of SPAM in them, and I�m not sure whether they is an abnormal amount but since it is the holiday season it could be. We have a McAfee Webshield serving as a SPAM Filter between the two servers, although nothing has changed in the configuration. One thing I have not noticed before are frequent messages sitting in the queues that have no header information � no Message ID, no To, no From, no Subject � completely blank �except that they typically have a size of about 40K. I cannot delete these. Exchange doesn�t give me any options to manage them. I don�t know whether this is related to the slow mail problem I am seeing. Any ideas about how to solve this problem?
