The message from the spool file 30N95PDH

I've seen something similar to this before, but I can't recall the specific circumstances. In our case, the IMS shutdown with (if I remember correctly) similar errors, and attempts to restart it would just result in more errors. We ended up pulling messages out of the internet mail queue (and copying them to another location) and restarting the service - problems solved. I don't know if that matches what you are seeing...it sounds kind of similar.
