Hmmm... Nobody wants to come to the party... Guess I'll keep my own
thread going in case anyone else out there ever has the problem...

Here are the vitals on my local sandbox environment:

Servlet Container Apache tomcat-5.0.24
Java 1.4.2._04-b05
JavaMail 1.4
JavaBeans(tm)Activation Framework 1.1

The following source creates an email message and attachment and sends
via javamail. All works well in my local sandbox environment. Mail
message with attachment arrive without a hitch.

I've been working with my host on why deploying this produces no error
messages, but no mail message either. They are perplexed. They have
linux servers running Resin. Does anyone out there see any
incompatibility here?

Wow, really dead in the water on this. Anybody out there using
javamail reliably on a web server? I've used it successfully
clientside. Have yet to see it send a message serverside. Seems like
there must be some kind of permissions issues on web servers that
restrict javamail. Is this just something people don't want happening
on web servers?

Is there some way to debug this situation? I keep reading about
sess.setDebug(true) but I'm unable to get the output back to the
browser to view. No exceptions are reported to me. Message doesn't
send and I get what appears to be a proper response back to my browser.

Trying to send an email with an xml attachment from a servlet (code
below) without success.

When I run my servlet locally all goes fine. The message is delivered.
When I upload to my host, messages are not delivered. I believe the
servlet runs fine because result data makes it back to my browser and
no exceptions are reported.

I've read that spam blockers will flag messages not really from the
server from which they claim to be. All is good here. The from is a
real account on my host's email server.

My host runs SpamAssassin. The message isn't delivered even when this
is disabled.

Any thoughts on this would be greatly appreciated.

Thanks
