This depends on which mail server you have. Are you using Exchange ? If so you can use the server name of the exchange server (you can see this in outlook). If your application has to be used outside the organisation i'd suggest you look for an alternative to send mails. The problem is port 25 is most of the time blocked by ISP's. You could ask setup SMTP on an alternative port and make forwarders from an @ ubos.org address to the yahoo and gmail addresses. This way you can connect to the SMTP server from outside without authentication.

Hi

I have tried Ihadi's approach and i get message "Unable to read data from the transport connection"

I have tried to understand what to do with robbe's solution and i cannot get through yet. How do i get the server name from outlook, i have failed. true the application is going to run on the local Intranet but i would also want to learn about the alternative methods.

Thanks
