The PIX issue that I remember cropping up (not for me, I wouldn't
touch one with someone else's bargepole) was around the PIX masking
out some ESMTP capabilities - possibly STARTTLS. I guess it masks them
because it knows it's going to break them - a proxy such as the PIX
acts would almost certainly break STARTTLS....
The solution was to turn off the SMTP fixup feature. Or trash the PIX.
