90% of the projects I work on need to send emails, and most clients don’t allow developer SMTP servers floating around their network (for good reason). So a big headache ensues trying to get access to an Exchange or SMTP server somewhere. I have been doing this same dance for years. But today I find a blog post about sending emails without an SMTP server. The .Net calls to SMTP just write the emails out on the file system. It’s just configuration even. So much to know, so little time.
