This is probably a simple question with a simple answer, but I wasn't sure where to look. I recently installed a deny-all firewall and everything is working fine. However, I keep getting /kernel log messages about attempts to connect to port 25. Are these just various processes trying to mail their results to root, but can't because of the firewall? Or maybe cron doing the same thing?
