[Dovecot] Using allow_nets

[Guy]

Hi,

I'm wanting to implement allow_nets so that some users can be limited to
only use webmail while others can use client or webmail access.
Adding the sql to pull a list of IPs/ranges for webmail only users was easy
enough. For the users that are allowed to access from anywhere, do I need to
specify 0.0.0.0/0 or something or can I just let the sql query return a
blank field?

Thanks
Guy
