Your Server

SMTP server for Windows?

Are there any free options for a simple SMTP server for Windows? What I need to do is send mail to the server from an application, and then browse the queue on the server. That's all. I don't need to actually have the server relay out the mails once it has received them. Browsing the queue is the important part. Of course, this task is simple if I had a BSD/Linux machine available, but I don't.

1. You may find it simpler to set up a direct session snoop and watch the SMTP traffic directly. You could do this manually, if you know SMTP (it's a very simple protocol) using a program such as RosMud. Download it (see source) and create a world in passive mode, with IP address 0.0.0.0 and port 25. Then when the application tries to connect, you'll get what basically amounts to a TELNET session, with the application as the client and RosMud as the server. (I'm assuming that since you know what to do if you had a BSD/Linux box, you'll be able to handle SMTP manually.) If you need further help with RosMud, feel free to pester me directly.
