Subject Re: Blocked thread in RemoteDelivery

Sending more detail on the dev listserv...


For a future version, I'm considering creating a separate thread to send
each message, and join to that thread for a certain number of seconds, so if
the message is not sent, it is aborted.  However, this creates extra
complication in the code, an extra thread created and destroyed for each
message (or even more complication to build a thread spool), and could cause
problems for large messages sent over a slow connection.

Any thoughts on a better way to handle this?  Again, if someone can figure
out what's hanging it, that's the best of all possible worlds.
