I was ordered to configure nginx as SMTP proxy. That's all details I have. I've looked though some books and docs and don't see neither any examples of such configuration nor explanations of why this might be useful. Probably, to handle SMTP AUTH through the http server to decrease load, I don't know.
Could someone point me to the sense of this setup? My nginx.conf is default, no changes made, I don't think you will ask me about it. Would someone be kind to share his experience of SMTP proxy configuration?
