Wouldn't be surprised, usually messages that get stuck in the pending submission queue is due to some third party app mostly AV. Prior to submission to the categorizer Exchange sends the message to AV where it is scanned and returned to the routing process. I've seen where customer installed a demo prod of AV and removed it only to see messages stuck in submission queue which was caused by event sink not being completely removed. ________________________________ From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Hans Maris Sent: Wednesday, July 19, 2006 4:39 AM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Re: Mails queuing, not been delivered We have a similiar problem. Mails get stuck in the following queues: - Messages awaiting directory lookup - Messages pending submission I can't find a system in the crashes/hangs...( they are not on regular basis) In out case it is the inetinfo (IIS) process that hangs, and crashes when trying to stop the services. We opened a case and are working with Microsoft to find a solution. I already installed a lot of debugging tools that collected a lot of logs, but it seems to be not easy to point to the problem... It seems to me that SMTP becomes irresponsive in 'a certain condition', some kind of mail that messes up SMTP ??? What I do to come quick online without robooting: - Kill inetinfo.exe - Resart services If we find some solution I'll let you know...

Do you recall anything being updated installed or changed? ________________________________ From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Dave stevens Sent: Tuesday, July 18, 2006 3:56 AM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Re: Mails queuing, not been delivered All services are running, and we have tried disabling Mc Afee, but no joy. Mails just seem to get stuck in the queue. The only way to get some of them moving is to reboot the server. Even trying to restart the sntp service would throw the server into an unresponsive state. This is getting pretty dire, and I am not quite sure what the problem is. I have instructed a reinstallation of Exch 2003 sp2. From what I can see the smtp service is not working as smoothly as I would want. Just wondering if it corrupt? I just dont know.
