Does anyone know of a free, anonymous smtp service? I want to give users of my app the ability to occasionally send me an anon email without having to configure a server of enter their email account. I guess I could setup a gmail account for this purpose and embed the credentials in the app but I hope it won't be necessary. In case it sways your answer, this is a thick client (.NET Console) app.

I think that what you're asking for is called an open relay.
