Cool, I did not now that either. I still have exim starting up in my
init scripts along with exim4. The exim script has this:
DAEMON=/usr/sbin/exim
NAME=exim
test -x $DAEMON || exit 0
But there is no longer a /usr/sbin/exim on my system since exim
was uninstalled when I installed exim4. Now I understand.
I finally got motivated and upgraded to Exim4 as well but I did
not go to the effort of using a backup MX. From what I know, most
good MTA's are built with redundancy and will try for a couple of days
before they drop any mail. My concern was being down and getting
automatically un-subscribed to all my mailing lists. That would be bad.
This is what I did for my Debian Stable server:
Added the following lines to my /etc/apt/sources.list file.
deb http://www.logic.univie.ac.at/~ametzler/debian/exim4manpages/ woody/
deb http://www.logic.univie.ac.at/~ametzler/debian/gnutls/ woody/
Then I did apt-get update, then apt-get install exim4-deamon-heavy.
(exim4-daemon-heavy includes exiscan-acl which allows one to actually
reject email at smtp time which is very, very nice)
It took a couple of hours learning how the configuration works as
it is totally different from Exim 3.
The debconf took care of the main isses such as what domains you
accept mail for, who you relay for, do you recieve via smtp or
fetchmail, etc....
I was worried about local delivery as I like to deliver to /home/user/Maildir.
Exim4 is delivering the same way Exim 3 did and I did not have to do anything.
Getting spamassassin working with exiscan took a while.
Mailman 2.1.4 was pretty easy to get working again.
I am finding that Exim4.30 is an excellent MTA.
Thanks to Andreas Metzler for the backport.
