Does anyone else get things like this in their linux firewall logs:
Jun 11 23:19:06 gShield (default drop) TCP mc8-m8.law13.hotmail.com:25 ->
Jun 11 23:59:27 gShield (default drop) TCP mpsb-nat30.plala.or.jp:25 -> 54606(54606)
Looks like when I send email, the SMTP server is somehow trying to connect back to me on the same port I'm connecting out on (the high port).
I haven't been able to find out anything about this on Google.
