Trying to switch from sendmail to postfix I did:
# yum remove sendmail
which resulted in erasing of: mdadm sendmail-doc sendmail sendmail-cf mutt fetchmail redhat-lsb
I did then:
yum -y install redhat-lsb.x86_64 postfix
and got this error:

You don't need to remove sendmail, you can just use system-switch-mail to set postfix as the MTA.
I knew that thx. I tested the exact same steps on our internal testmachine. Must admit it has EL5.2 x86_64 on it but did not show this behaviour.
