> Yes, We have a CISCO PIX in between.
The CISCO PIX has a long history of mis-implementing SMTP.
If you want to be able to send mail without such screw-ups,
you need to turn off their smtp f*up feature.
You are also welcome to send a copy of this thread to your
CISCO representative, so they can get this fixed.
