New Postfix.

Hi. I'm running SuSE linux 8.1 with the default Postfix install postfix-1.1.11-109. I would like to run the new postfix, but I'm a bit confused on how I shall do it. Of course I stop the running postfix, and by aid of Yast I can remove the running Postfix version. What have I to do after that removing ?. What files/directory shall be removed, if they were not done by Yast. Would have been nice, if the new Postfix was to be found as an .RPM package. Of course I can use Checkmail, as I do in some cases. Its not a fault that this message is sent to 2 mailing lists. Maybe some on the SuSE mailing list has good experiences with the subject :-) Thanks in advance for all answers. -- Erik Jakobsen
