I am having a problem sending email that is larger than 32k to an exchange
server.

If I issue the command mailx -v -s "test" email@address.com < some.file

The system appears to hang,and eventually times out. On one of my systems
a couple of the "test" emails have finally shown up after 2 hours.

I did find one message in the archives, but there was no summary, and the
possible fix it says
doesn't resolve the problem. ( setting pmtu_enable (inet module) to 0 )

Will summarize, and/or post an answer if this get resolved.

Thanks

Darren
