Hello, I'm considering upgrading Postfix on a Centos box from version postfix-2.3.3-2.1.el5_2 to a rpm compiled for another Centos box postfix-2.5.6-1.sasl2.rhel5.
The older version was installed as a part of the Virtualmin add-on package and uses Procmail for deliveries to virtual users and has Mailman incorporated as well, both of which I'm not familiar with. My question; is the master.cf file from the older version usable in the newer one? I feel more comfortable modifying the main.cf than the master and would like to leave that file as-is if possible. thanks, Chas.
