Is there anything special that needs to be done to get mail to be delivered through a PIX. The issue that I am seeing at the moment is that any mail that I sent to our listserv (Ie: command to get a list of our lists) never comes back to me. I see in the queue summary a large number of emails for our domain but they don't get delivered..... -----Original Message----- From: Al Iverson [mailto:[log in to unmask]] Sent: Thursday, May 03, 2001 11:54 AM To: [log in to unmask] 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
