One solution would be not tagging exim as important package. The mail server
is a personal choice and each administrator should be free to choose his
preferred package. Forcing exim installation seems a bit fascist to me.

Whenever I install a potato system I have to deinstall exim and install
sendmail manually. Besides having to install a lot of missing packages,
for example gpm, nfs, traceroute, apache, dpkg-www, this is very annoying.

Maybe we could mark the mail-transport-agent virtual package as important
and let the user or apt decide which real package is installed.

Another solution would be having the possibility to load a user defined
package selection list after tasksel has done its job. Here exim could be
marked for deinstallation and another mta selected instead.

The tasksel behaviour is very annoying on this point. There is no way for
the user to add more packages to the tasksel selection list. I have such a
list on a floppy but can't load it until the installation is completed.

Can we add to the tasksel postinst a prompt for loading a user package list
from a file?
