I see three options (in not particular order):
1) Make Postfix the default. Run it by default, but with a master.conf
which only includes the required components for local delivery (i.e. no
smtpd listening on port 25...). Provide an easy way to switch to a
'normal' full Postfix configuration, for those who choose to.
2) Make sendmail work for local delivery. Either by checking the config
(perhaps at the start of /etc/daily, confirm that local mail will work,
otherwise write warnings to syslog and the console, and/or deliver
output into /var/mail/root directly (ignoring any aliases).
3) Find/write a BSD licensed minimal LDA, and use it in place of 'mail'
in the crons and rc scripts that have this issue.
