Both of these messages are related to sendmail activity that is being blocked. You shouldn't be filtering your loopback, I would suggest something like this to get rid of those messages. ################################################################## # Basic setup - enable loopback, block 127/8 from non-loopback ################################################################## ${fwcmd} add 100 pass all from any to any via lo0 ${fwcmd} add 200 deny all from any to 127.0.0.0/8 ${fwcmd} add 300 deny ip from 127.0.0.0/8 to any The ::0001: are ipv6 addresses - I've never played with these so I can't give you any advice.
