Just installed XWALL on a different server. Now some of my users who have set up Outlook and Outlook Express at home are not able to get mail. They get an error: connection failed port 143. Makes me wonder if I have a comprimising setting on my Exchange server that is now tightened up using a spam filter. Should a user at home be able to set up Exchange without security comprimise? Also, if this is not a problem, does anyone know the XWALL setting to allow this. Thanks.
