Ever needed to test the e-mail functionality of your application, on windows, without having access to a SMTP server? Try SMTP server for developers, a brilliant piece of software, so far.

You need .Net for it. It’s really easy to setup and use. Another advantage of this SMTP server is that when you test your application, you don’t have to worry about test e-mails being send to customers. This because the SMTP server doesn’t really send the messages, but just places all of them on disk.

Update: one disadvantage. You can’t get it to run on any other port then 25, which is inconvenient if McAfee is blocking port 25. I contacted the author a while ago, but no response so far. Guess I’ll have to add this functionality myself, but then I need to get up to speed on .Net first. Ah well, I’ll wait a little longer.

Talking about McAfee… It’s kinda weird, it blocks e-mails on port 25 if I use for example Java to send the e-mail. But if I use telnet to connect to port 25, all is fine?
