Can you outline what happens?

you can put all four package names on a single command-line, but you
still need force-depends since you likely have packages depending on
m-t-a on your system.

Should be. You might want to look whether the Debian-exim account is
gone, and all files belonging to it, and whether /var/spool/exim4 and
/var/lib/exim4 is gone.

Depends. If what you want to use is with in Debconf scope, edit
/etc/exim4/update-exim4.conf.conf. If you want to do something outside
debconf scope, you either need to edit the appropriate file in
/etc/exim4/conf.d, or /etc/exim4/exim4.conf.template, depending on
whether you have chosen split or non-split config.

/etc/init.d/exim4 restart is enough, it invokes update-exim4.conf.

All known bugs are visible in the Debian BTS.

/etc/aliases is used for local domains only, so choosing "no local
mail" will probably not execute the system_aliases router.

exim -bt address will show you the routing steps for an address. Add
the -d option for lots of debug output.
