Using qmail in an RPM (or YUM) world...

I was trying to run 'yum update' on my webmail server, which runs the highly recommended qmailrocks.org distro. Well, to get it to stop trying to install exim / sendmail / postfix I was able to create a "fake_mta.spec" based on one I found online (but had to transcribe into a VM box):

# Use rpmbuild -bb to install this

A fake package so that qmail won't get hosed,
even tho RPM/YUM don't know about it.
