Port 113 probably does not need to be open for Imail's benefit.  However, when Imail attempts to connect to another SMTP server, that remote server a great deal of the time will attempt to IDENT Imail on port 113.  (It may also do a reverse DNS lookup on Imail, so that should be set up correctly.)  If you go to Google and type in "smtp port 113", you will see thousands of links to sites explaining the need for port 113 to be open. Hope this helps. Sincerely, Michael Keen http://www.inksite.com
