[Dovecot] Documentation clarifiction on mmap_disable

[Marcio Merlone]

Greetings,

On http://wiki.dovecot.org/MainConfig I read:

"mmap_disable = no
    Don't use mmap() at all. This is required if you store indexes to
    shared filesystems (NFS or clustered filesystem). "

Does that mean:

1. mmap is required when using NFS or
2. it is required to don't use mmap at all when using NFS?

Sorry if this is obvious. Best regards.
