I'm glad I guessed right, although I was about to post to dev since I
hadn't heard anything in a while. *Grins*
Thanks for the replies!

Is the only variation that the number of threads is configurable by the
admin? I assume in James 1.2.1, you have to hard code it before
compiling? In other words, that it supports multiple threads, but it
isn't admin configurable?

Does the SpoolManager handle multiple, simultaneous emails per thread?
I'm guessing not, since non-blocking I/O is new to Java 1.4.

Does the spawner of these threads modify their priorities at all or just
leave them at the default?
Thanks again!
