How to allow non-root users to run mailq?

[Neil Bird <neil@xxxxxxxxxx>]

  Is there a 'formal' way to let non-root users run mailq?  I'm 
currently doing it by making the sppl/mqueue dir. readable.

  I saw in the sendmail docs. that there's a 'don't let normal users 
run mailq' security option, but that doesn't seem to be in place, and 
there's no "DO let ..." opposite equivalent.
