Why? Having a predifined location for the inbox a requirement if you
are using MUAs that access the spoolfile(s) directly (mutt, pine, etc.)
and /var/mail is the location the FHS suggests.

Actually afaics /var/mail is no problem for installing different MTAs
at the same time, it is not owned by any MTA but generated by
base-files. And if you locate your mailboxes there, they have to be in
standard UNIX mailbox format (FHS) and are only accessed with proper
locking (policy).

/etc/aliases is no problem either, it is just kind of messy because
there is no central "policy" on what aliases should be in the in there
per default. /etc/aliases is not owned by any package.

Imho the real problem is port 25. Afaik the infrastructure for
installing two programs that might use the same port on debian is
missing: There is no "/dev/port/25 alternative" - no canonical
policy-conform possibility for daemonA to disable daemonB on
installation. (You cannot call invoke-rc.d -f remove ;-)

Just out of curiosity, could you name some examples?
