Issue Watchdog - IP used for probing services?

[105547111]

Here's a quick question. I'm filtering port 110 and 143 TCP only to my IP address as mail users STILL refuse to use secure GRRR.

Now watchdogs complaining about plain courier IMAP and POP3 as iptables is now dropping everything except my IP own address.

I'm guessing its probing on localhost, or does it use the servers host IP?

Anyone know?

Cheers!
