Well, I changed web server to be accessed from Internet over port 8383 and this has stopped the code red attacks. But the email server is still hanging the winsock (tcp/ip) stack every three days and requiring a restart of email server:

I don't know what would be causing this as there are no other clues in the imail log. This email server is in a DMZ which only allows SMTP,POP,IMAP,HTTP,HTTPS from Internet and additionally FTP from internal. Could it just be iMail itself causing the problem?
