Sender: owner-questions@freebsd.org X-Loop: FreeBSD.org Precedence: bulk As most of you know, I've been haunted lately by some nagging problems. I was looking at the filter tables in my Cisco 2501 and noticed some problems with the way it was handling ICMP. Could improperly managed ICMP filters cause sendmail to die on OUTBOUND mail only ? Perhaps the remote systems try to do a reverse ping back or something. I'm weak on the actual workings of ICMP except that I've been 'ping bombed' by competitors which was annoying. -Kurt .
