And I am not talking about the simple duplicates that result from someone CCing you as well as sending the mail to the list. I was seeing tons of duplicate mails from people just generally sending to the list on other topics too. Now I have been fiddling with my firewall today and I changed two rules: 1. I god rid of the rule for logging unclean packets - this was causing heaps of eroneous logs since I upgraded to a 2.4.14 (from 2.4.4) kernel. There is apparently a bug in the 2.4.14 kernel that caused this - so I just commented out this rule - which wasn't really necessary anyway. #$IPTABLES -A INPUT -i $EXT_IF -m unclean -j log_unclean (log_unclean - just logs and then drops the packets) 2. I added a rule to REJECT connection attempts to my ident port rather than just DROPping the packets. This means that I don't get 5 logs resulting from the debian mail server trying to identify me everytime I send an email to the debian-user list. Here is this rule: $IPTABLES -A INPUT -i $EXT_IF -p tcp --dport $IDENT_PORT -j log_reject (log_reject just logs and then rejects the packet) I can't for the life of me think why this may have caused me to get duplicate mails. Perhaps something to do with the - unclean packets? Maybe because they were DROPped that caused the mail server at the other end to re-send the whole message again? I haven't changed anything in my fetchmailrc, /etc/postfix/main.cf, or .procmailrc files. And yet it seems to have stopped now. Very confusing? Cheers. Mark.
