POSTFIX main.cf and master.cf config being modified/rewritten

Hello all,

I have been having problems identifying what is causing my main.cf and master.cf files to be modified by some process making my configuration immediately stop working.

The only thing I can say I have done on this machine is used yast2 to reconfigure a network route.

I have not got yast2-mail installed and have never used it to configure my mail but something keeps modifying my config files without my consent.

Can anyone help me stop the unwanted modification?

All my valid config is # commented out and new elements are added with blank values.

Is this part of some script I am not aware of?

I am strongly considering moving my mail server to another system because of this.
