I have a message that has and is stuck in a queue on my backend mail server. The queue is:

Internet Mail SMTP Connector (MY_FRONT_END_SERVER_NAME)-524350ff...

It is in state retry with 183 failures. It is only one message and all other mail is flowing. The message is not particularly large. My limited understanding, a guess really, is that this message should get handed off to the front end mail server and sent to the remote hosts for which it is destined, so it should even matter if the remote host is up. However, I can telnet to the smtp provider of that host.

How can I find out why it is stuck in this queue, and can I force it out somehow (unfreeze doesn't help me)?
