nginx as mail proxy

Question

I am trying to setup nginx as mail proxy. All i want is to let nginx receive the mail and forward it to a script. Is this set possible or should i only use sendmail for that.

Answer 1

The only way I can remotely imagine that working is if you would let nginx listen on the smtp port and run a smtp server web application on that port. At that point nginx would basically only connect the outside port to your locally running app. So yeah, I think you would be much better off with a real smtp server like sendmail. Actually, I recommend you use postfix because it does the same thing arguably better.
