I create a simple standalone app that has the following method in it for sending emails:
This method works perfectly if the SMTPServerName is set for my ISP's smtp server. But since I have my own in-house server now which is running Linux, I thought to try and make use of its Sendmail server instead.
So, I need to know what I need to change in my method, if anything, in order to send out emails through Sendmail. For starters, I consulted a book I have on linux which explains how to configure Sendmail as a relay to send messages out. I made those changes and restarted Sendmail. So that end is set.
Since the server is part of my LAN on IP address: 192.168.2.119, In my client app (on a different Windows computer withing the LAN), I tried setting the SMTPServerName to the IP address of my server running Sendmail. Then proceeded to send myself an email. That didn't work. I know Sendmail is listening on port 25 so I tried 192.168.2.119:25 adding the port number, but that didn't work.
So, what is SMTPServerName supposed to be if I'm trying to connect to Sendmail to send out an email?
Is the method adequate for what I need it to do, or do I have to change it?
