What do the logs show? Is this a relay or does mail originate on this server and get sent out? Has this server ever worked or is it new? Can you telnet to it on port 25? Does it accept mail and just not forward it or does it not even answer on 25?

I can recive email with pop3 evreywhere . i can send email from my server but i cant send from my pc with outlook express. I get this message :

Send test e-mail message: Outlook cannot connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).

i did contacted my server administration and told them PTR reverse zone for my server and they did it. if you go here(http://www.intodns.com/isolatedserver.com) , you will see that evrey thing works fine.
May be i doing somthing wrong with dns ? but as you see on intodns website all works fine .

Thank you for helping  .

check your smtp connector settings
