[rhelv6-list] mingrate sendmail to postfix

[Alois Treindl]

My new RHEL 6 installation does not contain sendmail as a service, only 
postfix.

Are there any instructions how to migrate a sendmail mail server 
installation to postfix?

In my case, this includes in /etc/mail these configuration files
sendmail.mc
   with settings for procmail, for rbl-plus.mail-abuse.org, for 
sbl.spamhaus.org, for avmilter etc

Or can I continue to use sendmail as MTA on RHEL6. If yes, how to 
configure at kickstart install?
