I would definately be intersted in hearing more about this. We just switched
over to a Pix here in our office and I am having nothing but issues with the
listerv and mail coming back into our office! I thought it was a bad DNS
entry but this makes me wonder even more!

Subject: the Cisco PIX firewall bug


Every once in a while we run into a user who claims we're mailbombing
them, and invariably it's a Cisco PIX firewall, as outlined in the
support FAQ.

Unfortunately, the onus generally rests on us, as to why are we are
"letting" our listserv & lsmtp servers do this.
Is there *anything* we can do on our end to proactively prevent this
situation from occurring? I'd love to hear that there was a patch for
LSMTP or LISTSERV that will allow the servers to work around the problem
when many asterisks are recognized in the SMTP banner.

All I can do on my end is disable any further mail to that domain until
the admin gets their stuff together. Which is rare, and I'm not in a
position to push them around.

Any info would be appreciated.

Thanks,
Al Iverson
