Postfix is the MTA, but the file itself is NFS shared between all the
mailservers, and furthermore is used as part of a script that expects
things to be "just so."
I inherited this setup, and don't dare start changing the permissions on
key files until I understand what every part of the equation expects to
see-- an example would be the user mailboxes, wherein the permissions
were set incorrectly causing Sendmail to choke (dontblamesendmail has
more on this for the curious).
