/var/log/exim4/mainlog has many lines such as this.

And this.

Not at all illuminating.  In any case, the blockage appears to be
merely wrong port usage.  See below.

The suggested aliases have been present since exim was installed years
ago and nothing has been removed.  The problem now is to make exim4 work
with a fresh ISP.

OK, thanks.  I'll give attention to /etc/email-aliases soon.

With tls-on-connect, swaks sent a test message.
So a current challenge is simply to make exim4 assign ports to
interfaces correctly.  I suspect that correct port usage will
allow messages to be sent.

My intention is that exim4 receives local SMTP connections on port
25 with no TLS and calls the remote SMTP server with tls_on_connect,
port 465.

http://www.exim.org/exim-html-current/doc/html/spec_html/ch-encrypted_smtp_connections_using_tlsssl.html
admonishes,
"You still need to specify all the ports that the daemon uses (by setting
daemon_smtp_ports or local_interfaces or the -oX command line option)
because tls_on_connect_ports does not add an extra port – rather, it
specifies different behaviour on a port that is defined elsewhere."

Well, according to "find", daemon_smtp_ports doesn't exist.
root at dalton:/etc/exim4# find . -type f -exec grep "daemon_smtp_ports" '{}'
\; -print
root at dalton:/etc/exim4#

And local_interfaces is assigned whatever lurks in MAIN_LOCAL_INTERFACES,
regardless of my intention.

Can anyone advise how to assign ports according to my intention stated
above?

Thanks,                  ... Peter E.
