Hello,
I was asking myself about the kind of connection used by a MTA to
contact another one.
For exemple, I know that we can setup in a MUA an SSL (or TLS)
connection when configuring the SMTP connection. So the connection
between the MUA and the MTA is encrypted.
But can we configure postfix in some way to ask by default an encrypted
connection when sending mail to others MTA? Or maybe it already do it by
default?
So we may have something like that :
MUA -----------> MTA -----------> MTA ------------> MUA
encrypted encrypted encrypted
I know we can't guarantee that the entire flow will be encrypted because
we only have control on our MTA.
But is it possible?
Thank you,
