Last month we had a similar thing happen. Turned out to be a 1MB PDF attachment was bombing the SMTP service in 8.01. 8.05 fixes this. You should see errors in the logs showing SMTP delivery failure after a particular email. Removing the Q* and D* files for this email from the spool directory should let everything go through, though we restored spool files in batches to monitor. The SpoolViewer utility is useful for monitoring this.

We are running IMail 8.00 on a Windows 2003 Server. It supports over 200 hosts with about a total of 1000 accounts (not a ton of traffic going through here) Up until yesterday afternoon it had worked *perfectly* for the last 6 months... There were no recent server restarts or config changes that would have caused this to stop working. About 6pm on Monday evening, people started complaining about mail delivery and not getting messages. I checked and found that the Queue Manager service was using quite a bit of memory (132K) when usually at a normal pace it uses (10-20K). I restarted the queue manager service and then noticed how many messages were waiting in queue (5000+) and monitored the process, it looked as though it was processing the mail fine, so I let it go overnight hoping that by morning it would be through the 5000 emails and all would be good... This morning when I came in... there were 9000+ messages and the service had peaked out again... (132K)... after restarting the service and reading an article on the IMail Knowledgebase, I moved everything out of the spool folder into a 'save' folder and then verified that messages were sending fine and fast again... I have since been moving chunks of email at a time from the 'save' folder back in to the spool, every so often while checking the Queue through IMail I notice messages that have no sender, no recepient and no file size... I'm wondering if these bad messages could be causing my issues... more so... I'm wondering where they might be coming from... Any of your thoughts on this issue are greatly appreciated... I don't have warm and fuzzies about leaving the machine unattended at all this evening... but I still need to put another 3000+ messages from yesterday into the queue to be sent out at some point today...
