Disable mail server check - as we're running Exim


We’re running a modified exim/courier-imap installation that can’t be changed.

How can we stop the installation of GPL Virtualmin requiring a mail server? I tried modifying the virtualmin .pl script, but couldn’t find the error anywhere.

If at all possible - can we also link it into Exim? I believe the question was asked over a year ago - so thought i’d ask again.
