Some Mail stuck in VS1 queue

Posted on 2008-10-27

Exchange 2003 server SP2 (SBS 2003 SP1). A number of eml files (outgoing mail) remain in the VS1 folder while others pass through fine. The stuck files all seem to be spam but hard to tell as 90% of all mail is spam.  If I kill iinetinfo.exe in task manager (and it restarts automatically) these files are released.  Sometimes, about once a week, all mail stops until I kill inetinfo.exe. Restarting the IIS admin service does not work but killing the exe file does.

If you look in Exchange System Manager, expand SERVERS and expand SERVER_NAME.  In the queue menu option, you will be able to see where the mail is stuck,. and it will give you the starting point of where to troubleshoot it.

Thanks markusdamenous.  All queues are empty and 'ready' but there are still 55 files in the VS1 queue.

Can you open them with outlook express on the mail server? this should give you an idea of whether they are spam or legit.
Sounds as if something is progressively clogging up inetinfo...?
Problems using Powershell and Active Directory?

Forgot to mention - we are running Spamfighter but I do this on other servers without the same result. Spamfighter has been uninstalled and re-installed as has AVG V8. Not running Exchange version of AVG8 and have excluded VS1 folder from scans and realtime checks.

Had a good read.  I don't get high CPU and memory usage increase to about 60 MB but not too high.  I have already re-installed antispam software and there is no antivirus software linked to exchange

A bit more data for anyone who can help:  I tried moving the files from VS1 to another folders but the files were 'in use'. I started stopping each Exchange service to see which was 'holding' the files. Eventually found I could not stop the SMTP service - it would not respond to a stop request. I then used my normal trick - killing the inetinfo.exe program. This cleared the folder and restarted all the services.

Cause found, still need solution. The cause of the problem is the sender ID filter. This seems to be the problem described in MS Article 905214 - Windows Server 2003 may stop responding when you enable Sender ID filtering on an SMTP virtual server in Exchange Server 2003 SP2. however the required patch has been applied but the problem persists. By turning the Sneder ID filter off, the problem is fixed but I would like to use the Sender ID filter.
