Re: javamail code in servlet works locally, but not when uploaded to host

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
