exim 3.x and 4.x
================
This is a package of exim 3.x. This is no longer supported upstream, and only
remains in debian to support users with existing exim 3 installations. We strongly
reccommend exim 4.x (which is in the exim4 package) for new installations. We
suggest users with existing exim 3 installations consider upgrading, particularly
if they have fairly simple configurations.

New libdb version
=================
This version of exim uses libdb2 databases. The version you are
upgrading from used libdb 1.85. Unfortunately the files are not
compatible. The hints databases have been updated, which should not
cause any problems, however it looks like your configuration file
refers to some other database files. If this is indeed the case, you
should rebuild them as libdb2 databases.

cat <<EOM
This may be important
=====================
In the version of exim you are upgrading from, the startup script
(/etc/init.d/exim) was set up by default to not run exim. In the new one,
it will run exim as a daemon if you are not running exim from inetd, and
you appear not to be.
If you have edited your startup script then you can ignore this message.
Otherwise, if you do not want to run exim as a daemon, you will need to edit
the startup script.

Important! Exim configuration file format has changed!
======================================================
Your old configuration file has been renamed to /etc/exim/exim.conf-pre-v3.
An automatic conversion script has been used to write a new
/etc/exim/exim.conf for you.
However, this does not fix everything, and you should check it is OK.
Because a wrongly configured mailer can cause serious problems, exim
is now disabled! When you want to re-enable it, you should do
"eximconfig -i".
Please read /usr/share/doc/exim/README.UPDATING.gz for more information.
