I'm doing some exercise with exim (4.80-7, debian wheezy) enabling SSMTP
(port 465) and authentication.
Final objective is to open port 465 to all the net, protecting it with some
stuff like fail2ban.
With my first experiment, seems that exim reject lately the email (even
without auth), simply does not route them (relay denied).
There's some way to insert, very early, an ACL that simply reject email if
unauthenticated, and only for port 465 (port 25 used only for internal
traffic)?
I've tried to find on the net something about that but probably i'm missing
some keyword...
