As for listeneing:
Package configuration
Please enter a semicolon-separated list of IP addresses. The Exim SMTP
listener daemon will listen on all IP addresses listed here.
An empty value will cause Exim to listen for connections on all
available network interfaces.
If this system only receives mail directly from local services (and not
from other hosts), it is suggested to prohibit external connections to
the local Exim daemon. Such services include e-mail programs (MUAs)
which talk to localhost only as well as fetchmail. External connections
are impossible when 127.0.0.1 is entered here, as this will disable
listening on public network interfaces.
IP-addresses to listen on for incoming SMTP connections:
127.0.0.1________________________________________________________________
That has been the setup since 2015 when I began using the
ISP's mailer.
