perhaps instead of asterisks, the banner should be replaced with 

220-This SMTP session is being munged by a cisco firewall that is

220-to be in the firewall, rather than your mail client or the server.
220-If you don't like this, contact our marketing department
220-and they'll explain to you that things are really supposed to be
220-this way.  Of course they're all lying bastards, but it's easier
220 to believe them than it is to stop selling buggy products.

With my cisco hat on:

- I know of historically three issues with the PIX:
  1 The greeting message
  2 (Proper) ESMTP handling
  3 Problem with terminating '.' in the data command when the bytes
    CR,LF,.,CR,LF ends up across a packet boundary

Number 3 is fixed in a release of the software released in june. People
should definitly upgrade. Fixed releases are 5.3(2) and 6.0(1).

Number 1 and 2 are still on my list...

I'll keep you updated, and I am happy if all of you (privately) keep me
updated on your experiences. I know you are unhappy, I am unhappy myself,
but people writing the code seems to now be able to "do the right thing".

So regardless of how bad you feel, if you have time to write down what you
have found, send it to me personally.
