At least it is rather cumbersome to install "by default" a different mta
on a large set of Workstations.

The majority of computers to be installed would not be mail-exchangers
or pop-toasters, but "end-point" workstations.  Having an mta installed
on them by default is a security risk or aditional work for the system
administration (or user) because

 a) local delivery has to be insured to get the whole bunch of system
    logging (logcheck), cron, at, etc. to work.

 b) The incoming SMTP service has to be disabled

nullmailer is not precisely a candidate for toy machines, because it
needs a remote MTA where to send all the (system generated) mails to.

Well at least in my setups, where a user or "sysadmin" account gets all
the system stuff.

It's a pitty there is no delivery-only mailer available in Debian.

Such a thing(y) could really be installed as default MTA: all local mail
will be delivered to local user accounts,  remote mail is bounced to an
administrative account (or to some kind of outgoing queue).
