amavisd.conf is rebuilt on every restart - as are many other zimbra configuration files. When zimbra restarts, it uses the information in whateverConfFile.conf.in to rebuild whateverConfFile.conf

In order to get a configuration change to stick, you need to edit the equivalent ".in" file.

So, in your case, you will need to make your changes to amavisd.conf.in
