Yes please. As I see it. Enable smtp fixup protocol on your cisco pix
(you will need to have a smtp server to point it to), then on some
linux system running with a kernel greater than do a telnet to
the smtp server that is firewalled and try to issue a smtp command.

Note that cisco has a bug report on smtp fixup banner hiding issues in
cisco os 6.3.4 but it should not result in the connection getting
dropped, it also does not explain why this problem does not seam to
exists on kernels prior to 2.6.9.
