- Administration » Exim4 SMTP Auth for the Real World
-
I tried several times to get SMTP authentication working for use in a modern environment with much wailing and gnashing of teeth. For starters, I don't want to have to authenticate every client on my LAN. Clients coming from my home subnet should be trusted by IP and should not have to authenticate. Secondly, I want to be able to relay mail from any client if that client authenticates via TLS from anywhere on the internet. Hopefully this will save other people some time and sanity.
