Thank you. I also found that '$-' is matching 'no SASL user'.

I'd say this isn't a bug - an empty username is still a unique value.
You should arrange your policies so that you aren't tracking quota on
SASL username for incoming mail.
Some modules apply all matching policies rather than the highest
priority only. So I figured out ages ago that the best technique to
use is to make all your policies mutually exclusive so that a message
will match only one and there can be no confusion over which modules
will do what. IN particular, the quota module applies the quota for
all matching policies - not the quota for the highest priority
matching policy.
So, I have a policy for inbound mail, with a member specification of
"!$*,!%internal_ips" for source. This matches where there is no SASL
username, and it's not an internal address (actually only 127.0.0.1).
Then for outbound, I have two policies :
"$*,!%hi-vol-sasl,!%Our_Network" and "%hi-vol-sasl". hi-vol-sasl is a
group into which I can put the SASL username of users permitted to
send a higher level of mail - and by excluding this group from other
policies, it avoids any conflict there.
I have another policy for internally generated mail (ie from our own
servers) with members of "%Our_Network,$*,!%hi-vol-sasl".
So that's 4 different policies, all mutually exclusive - and you can
configure the modules for each policy safe in the knowledge that you
won't have problems with multiple matches.
