Just a thought...Could it be caused by a blocking socket issue? If that's the case, setting a timeout on the socket would resolve the problem nicely. I think it would be better to figure out why the thread gets "wedged" rather than working around this problem.
In general, rather than launching too many threads (it gets really costly on the system when you get too many), why not have only one thread feeding from a queue? You could also add a watchdog thread monitoring the email sender. If the watchdog sees that the sender is connected and has not done anything for too long, the watchdog could then close the socket connection to the email server forcibly, hence removing the "wedge" (assuming that problems occur because of blocking sockets). My 2 cents...
