Author Files Stuck in SMTP Queue Folder

All,

Apologies in advance for the redundancy with other posts on this same
topic.

I've been reading those threads, tried nearly every suggestion I've
read about, and I still have the problem. When I try to delete the
message files in c:\inetpub\mailroot\queue\ using Windows Explorer, I
get a "...being used by another program..." error message. I've tried
stopping & restarting SMTP services, disabling the McAfee A/V, and
changing the order of DNS servers on the NIC's (two, LAN & WAN),
including various permutations of combinations of all of the above.

All of the messages are delivery status failure notifications from
postmaster@mydomain.com to spammers, whose original emails were to
email addresses that don't exist on my domain.

The logs files don't appear to help, so I've just set them to capture
everything, not just the default info.

Here's the basic scenario:

W2K3 Standard SP1
Vanilla IIS6.0/SMTP locked down to relays (disallowed)

I also located an interesting KB article (836833) RE: Exchange,
describing the identical problem to a tee, except that I'm not running
Exchange. I'm just not ready to spend $99+ to get the hotfix described
in the article before I'm sure it will fix the problem.

TIA,

Mike

Have you tried just moving the item(s) to the "Badmail" directory
instead? I had the same problem, I pretty much shutdown all the "smtp"
related services and yet, it gave me that error.

I can't move the files because I still get the "...being used by
another program..." error, even after shutting down SMTP services &
the antivirus! Very frustrating.

Just as a follow-up, I set the SMTP service to manual-start & rebooted
the server. After the server restarted & with the SMTP service /not/
started, I was able to delete all of the files in the queue folder,
after which I reset the SMTP service to auto-start & started it.

This behavior leads me to believe that the Protected Storage service
may have ultimately been the culprit. The reason I suspect it is due
to the fact that, to replace an active COM DLL, you have to stop this
service (which, in turn, shuts down IIS & all related services).

When the queue folder gets overloaded again, I'm going to try stopping
Protected Storage (noting all of the services I'll have to restart
afterward) to see if I can delete the queue files without restarting
the server. I'll post my findings.

No joy on stopping protected storage service. Once again, I had to set
SMTP service to manual start, reboot the server, clean out the queue,
then restart the SMTP service.

Any MVP's out there have any clues? Am I posting to the right NG?

TIA
