Mail sending from VFP9 through internal postfix esmtp server.

hi all,

please help me in this regard. I am VFP 9 programmer. I want to send the mail from within VFP 9 application. I have used CDO of microsoft which is working fine. however to be able to send the mail i have to setup the router gateway on user machine which enable him to surf through the net which we did not want. we are having postfix ESMTP server (ubuntu) as mail server. VFP 9 application is running novell netware. Opera brower is being used in orgonisation to access mail server.

so please help me for following two things

1) how to send the mail from VFP9 application using postfix ESMPT server (ubuntu) .
2) what setting is to done so as user can send the mail however cant surf through the net.

Thanks in advance
