Just a little more information.
When I restart the queue service, the _{message_ID}.~MD
files are usually instantly renamed to Q{Message_ID}.RMD
I've never seen an .RMD extension --
anyone?
Also, I've noticed a few D{ID}.RTF and D{ID}.NTF
extensions.
Anyone seen these before?
It sounds like running Dr Watson and how it interacts with SMTP is
causing the issue and disabling it might help. I'm not sure how
though.
I have never had this issue (knock on wood), and I have
certainly processed enough E-mail for me to have hit a file that SMTP chokes
on. Our spam blocking performs very well, so it may be that broken
messages are killed by Declude (we have filters for broken/partial
messages).
Since we started gateing E-mail through MS SMTP with ORF,
the issues with spool files being locked for hours disappeared. This
eats up threads and might also contribute to the crashes. We have
configured MS SMTP to timeout after only 1 minute, and as a result, there are
never any of these locked files older than 1 minute in our spool whereas there
used to be many of them. We have only been doing this for about 2
months, so it isn't solely responsible for the fact that we haven't seen this
instability.
Also, once I helped another administrator fix their
issue. What was happening was the IMail Monitor was rebooting SMTP when
it was unresponsive, and it would occasionally cause the server to hang (about
once to several times a day when it started out of the blue). Turning
off the Monitor fixed the problem since the SMTP service was only
non-responsive as a temporary condition, and Monitor was causing the hang by
forcing a restart of the service without properly killing the process. I
don't run Monitor, and SMTP hasn't crashed on my server in my recollection,
even when the server was redlined at 100% for an hour.
Hope this
helps.

More specifically, I'm seeing the messages getting stuck as
_{MESSAGE_ID}.~MD
Imail's support page says these messages are queued for delivery for 2
hours. Problem is they just stay there.

If I rename the _ and .~MD message the message goes out but it is NOT
scanned by Declude. (Nothing's in the SMTP header).
We have the queue manager skipping domains and dns cached disabled
(unchecked).
Any thoughts?

What version are you experiencing this with? We had the same
problem with a PDF that IMail choked on. Updating to 8.05
HF3 fixed it for us, and we haven't seen it since.

I have just spent the last 24 hours slowly feeding messages back into
the message queue after queue manager quit delivering. It has happened
before, and I have seen posts on the Imail list discussing queue
manager hanging. The real problem is, the service is running, it just
isn't doing anything.
