SMTP Server For Developers

Version 2 (SMTP Impostor) now available

When I moved my development machine to Vista I soon realised that there was no SMTP Server included as there was in XP Pro

So… I got to writing one and this was the result

It doesn't actually send e-mails, it just emulates an SMTP server and writes the e-mail to a given directory

This allows you to test the e-mail functions of the applications you are writing

It can be deployed to any machine on your network and act just like the real thing… except for the sending bit, as mentioned

In a bid to engraciate myself on the larger development community this is an Open Source project, horrah!

For .Netters you can simply add a setting to your Web.Config, but where's the fun in that
