Hello,
Today was rainy so I forked Guerrilla-SMTPd server to create a fake SMTP server with a minimalist webmail client. Mails are neither relayed nor stored into a MySQL db (but temporarily in tiedot). I changed the command line interface to make it run either as a service or as a command. And I changed the interface to nginx. Now it can run through FastCGI or as a standalone web server.
The interrested of the thing is to get a SMTP optimized for load testing or for a demo of an application that send e-mails (they disappear after a while). It was inspired by smtp4dev but with web and performance in mind.
