I live and die by IDA, and strongly recommend it to anyone dealing with
sendmail on a regular basis.

But its dbm utility doesn't do the job.  We (and many other sites)
often have heirarchical aliases -- mail to `all' is aliased to
departments, departmental mail is aliased to groups, group mail is
aliased to people, some of whom have their secretaries copied on
everything.  Doing 'dbm fetch all /usr/lib/aliases' would only list the
first level.  Even doing multiple probes would not get a full answer,
as it would not interpret aliases of the form "include filename".
Using the printalias scripot script to drive sendmail and get the
complete interpretation is the only full correct answer I know of
without requiring a suid program.

Plus the slow correct answer is better that fast wrong one.  :-)
