Our company would like to start our own SMTP server in house for email marketing. Unfortunately the information we've found so far to do so seems kind of contradictory to other sites we found with information. What would be the best way to do your own SMTP server? What hardware/software requirements are needed? We plan on using SendBlaster 2 as our mailing program. We're working with our ISP to see if the ports needed are open (25 is the port we need from the research I've found) and we're trying to get them to give us a static IP address. I'm probably overlooking lots of stuff here as I'm completely unfamiliar with any kind of networking. Sorry for the noob questions, and thanks in advance for any help/tips you guys can provide.
