Nevermind, I figured out what my error was. I was trying to block that IP, and allow other smtp traffic through, but I did it in the wrong order.
Now I'm seeing where these things are coming from, and this is what I'm seeing: Packet log: input DENY eth0 PROTO=6 211.108.38.83:3868 my.mailserver.ip:25 L=40 S=0x00 I=2716 F=0x4000 T=108 (#3) Packet log: input DENY eth0 PROTO=6 211.108.38.83:2856 Packet log: input DENY eth0 PROTO=6 211.108.38.83:2119 Packet log: input DENY eth0 PROTO=6 211.108.38.83:4700 Packet log: input DENY eth0 PROTO=6 211.108.38.83:2226 Packet log: input DENY eth0 PROTO=6 211.108.38.83:2999 Packet log: input DENY eth0 PROTO=6 211.108.38.83:3781 Packet log: input DENY eth0 PROTO=6 211.108.38.83:1469 Packet log: input DENY eth0 PROTO=6 211.108.38.83:3781 What could be generating this? I mean, what program (on their end) is sending stuff from all those ports, and trying to connect to my smtp port? -- W | I haven't lost my mind; it's backed up on tape somewhere. +-------------------------------------------------------------------- Ashley M.
