Description of problem:

[root@josiah ~]# yum -y remove exim
[root@josiah ~]# ls -l /usr/sbin/sendmail
ls: cannot access /usr/sbin/sendmail: No such file or directory
[root@josiah ~]# alternatives --display mta
mta - status is auto.

Current `best' version is /usr/sbin/sendmail.sendmail.


I *think* the problem is that the alternatives removal in done in %preun, before the files are removed and so alternatives thinks exim is still installed.

I'm also surprised the default appeared to exim in the first place.
