The most important of all the documentation
on configuration of exim.
Richard Feynman's Dictum of Education: begin
with the most general concept and progress to
the more specific.
The documentation for configuring Exim should
begin with 2.1.4. After that, explain the

This most convenient documentation I've found is
Parameters covered in this chapter.
I haven't found a Debian specific version.
Which of the parameters gets a "dc_" prefix
remains a mystery.

The indirection is killing me! Which of
the upper-case parameters should define the
command line parameters? What quoting is correct?
Something such as one of these?
COMMONOPTIONS='-tls_on_connect_ports = '25 : 1025' -tls-on-connect'
QUEUERUNNEROPTIONS='tls_on_connect_ports = '25 : 1025' tls-on-connect'
QFLAGS='-tls_on_connect_ports = "25 : 1025" -tls-on-connect'
SMTPLISTENEROPTIONS='tls_on_connect_ports = "25 : 1025"
Rather than spend hours trying to establish
a working syntax by trial & error I put
these two lines in /etc/exim4/exim4.conf.template
at the end of the section marked "main/02_exim4-config_options".
daemon_smtp_ports = 25 : 1025
tls_on_connect_ports = 1025
Then I ran "dpkg-reconfigure exim4-config" again.

Well, I aim for port 25 to receive a connection through
my LAN while port 1025 is to receive a connection through
a legacy-SSL tunnel through the Internet. The problem
was explained more thoroughly in my message to
exim-users at exim.org between the 16th and 22 of
March, this year.
With the above configuration, this line appears in
2007-04-16 08:34:34 exim 4.63 daemon started: pid=11224, -q30m,
listening for SMTP on port 25 (IPv6 and IPv4) and for SMTPS on port
1025 (IPv6 and IPv4)
(Line broken for legibility.) At least exim
appears to respond to the lines added to
After this change, the local MUA continues
to work. Yet the SSL tunnel does not work
for sending and there is nothing pertinent
Any suggestions for settings additional to the two

Thanks. I'll look for the revisions after the next system
