[DPKG] how to change a package which is depended upon?

["Magossa'nyi A'rpa'd" <mag@bunuel.tii.matav.hu>]

Hi!

I want to change my MTA from sendmail to qmail. How to do that?

When I want to install qmail, dpkg says that I can't do that because
sendmail is already installed as a MTA. If I want to uninstall sendmail,
then it refuses because a lot of package depends on MTA. I've tried
--auto-deconfigure, but seems not to have any effect.
