Do I need to open the SSL port for this error? No, you don't need to allow SSL - that's why it says "Secure(SSL): No" - it is not using SSL. The solution is to upgrade your mail client - getting them opff Outlook will solve an awful lot of other security problems as well :-) If they don't want to run Kmail, Mutt, Mozilla etc, try them with something like Pegasus or Eudora... Antony. -- 90% of network problems are routing problems. 9 of the remaining 10% are routing problems in the other direction. The remaining 1% might be something else, but check the routing anyway.
