Thanks for the reply guys,
But i don't think i quite understand what your getting at with the
DNS stuff. The server is on my school's campus, and im using the campus
SMTP server. Im able to send email using the same SMTP just fine from
non-tomcat applications on the same server. I also don't think it has
anything to do with the actual SMTP server since the problem goes away
if I restart tomcat.
As for wireshark, this is a production environment and im not really
supposed to be installing programs on the server. Are there any
built-in utilities that might give the same effect? maybe like
tcpdump? if so what cmdline args would I run to get the desired
information?
Thanks

Heres my theory.... check the DNS on "your" mail address.... I have a
feeling that if the mail server cannot resolve your mail
address "domain"...
it will refuse the connection on a send.
... so if the DNS server is giving problems... your email goes to the
dogs... maybe.
A Wireshark trace taken from the SMTP server point of view should be
quite illuminating.
