Exim and Majordomo

I had majordomo up and running with sendmail. Since I installed exim it
has ceased to work and messages intended for majordomo get stuck in the
queue. What have I done or need to do?

I suspect something needs enabling in exim. Majordomo is set up in the
aliases file to redirect mail to a program.
