Hello,
I’m running as root and want to send notifications to remote addresses.
I’d like the first “Received” header to show “esmtpa”, but it appears that in
order to do that I have to authenticate. Since I’m root and can control the
server it seems like this shouldn’t be necessary, but I recognize that if IP
connections are the only option to send SMTP, then authentication is necessary.
What if, though, Exim could receive SMTP via a unix socket? Exim could
read the socket’s peer credentials on accept(), and if those credentials
indicate that the client socket was created as root, then Exim would be
justified in considering any SMTP message received from that socket to be
authenticated.
It would also be a slightly faster interface into Exim since the
connection wouldn’t have the TCP/IP overhead.
Has anything like this been discussed previously?
Thank you!
