(If you have fwlogwatch installed in your systems it can be easier to read the SFW log. Take a look in http://fwlogwatch.inside-security.de/)
Email is never sent from port 25. Email is sent to port 25. The above message (which is likely to be a consequence of another problem) arises during reception of email from a remote server. Maybe the remote server disconnected prematurely, probably because of waiting too long to get a reply. I doubt it's a firewall problem because mail does go through at times. So the real question is why does the mail server become unresponsive. The answer may be in the mail logs (/var/log/mail ?) John
Can you do a
ps auxww | grep postfix
and send the result
