New SMTP server and its first real world showcase

Hi there,

On year ago I was installing my server and I needed a SMTP server. I've tried sendmail, postfix and qmail but either I always got lost in configuration nightmares (I just wanted virtual users handled by SQL), or weird errors (qmail not recognizing my subdomains). So being the Lua freak I am, I decided to make my own, in Lua :)

And so it was born, and now one year later I've decided it to be mature enough to suffer the thunders of the outside world, so I present it to you, Tethys, my lua SMTP server designed to be easy to configure, light, extensible and simple (obviously it probably is only to me :) ).

And while I was in an SMTP mood I made a temporary email service based on Tethys, MailCatch.com. I thought this would be the best way to test out if Tethys can handle a nice load :)
