Yes, I converted from Exim 3, using the convert4r4 script.

Because I didn't think of that. :-)

I've now added a comment to my exim.conf, reminding me to
look in /usr/exim/src/configure.default for documentation.
I put it right under the comment which reminds me to "see also
/etc/exim/sa-exim.conf and /etc/mail/spamassassin/local.cf
and /etc/aliases". This is my coping mechanism, since I fool
around with Exim's configuration so seldom that I tend to
forget advice like this by the next time I need it.


My thanks to all who answered, and especially to Stephen Gran,
whose answer solved my problem, and to Philip, for a great
program!

P.S. -- Am I correct in concluding that there is no way to
directly address email to a server on a port other than
port 25, and that the only way email can be sent to a server
that is listening on an alternate port is if a port forwarder
or specially configured forwarding mail server forwards it
there, and that syntaxes like user@[209.170.129.106:26] or
user@???:26 are illegal, and MX records cannot
refer to a port number?
