is it possible to send email eventhough in LAN connection using Microsoft outlook ? is it programmable in VB.Net?
can someone teach me? thank you !

If you had a SMTP host on the network, you can just bounce the email off of it.

(Assuming it is configured to allow it)

though it is in LAN ? can you explain it further? :) thanks

If you have a host, like an Exchange server in the local netork - You can simply bouncing an email off of it.

Example

OR

If the server is configured, you can simply set a from address and bounce it off of the port/IP address.
