The mutable (changeable) directories are those in the VAR_PREFIX (set
by the configure --with-var-prefix= option) directory as opposed to
the PREFIX and EXEC_PREFIX directories. These directories are
archives/, lists/, logs/, locks/, data/ and spam/. The ones that must
be shared are archives/, lists/, locks/, and data/. The spam/
directory is only used when a message is 'preserved for the admin' in
the admindb interface. That and the logs/ are probably best shared.
Other directories can be shared or not except if the separate
instances have separate mm_cfg.py files, then the Mailman/ directory
needs to be unique per machine.

Correct.

Correct again.
