I have installed Qmail on a Linux box at may home. I have DSL and a 4 port router using NAT to direct all SMTP and POP3 traffic to the Linux box. I set up qmail and pop3 without any problem (or at least is all seems to work), but I keep getting the following error on the console... IP_MASQ: reverse ICMP: failed checksum from 4.0.84.250 Am I loosing (bouncing) mail when this happens? Any ideas on how to fix it? TIA Bill
