LDAP Entry for mailquotasize is missing... so far so good.

Here comes the interesting part, ldap "userdb" has returned
"QUOTA_RULE=*:BYTES=" and this empty value seems to correspond
to 0 Bytes as you can read from the resulting Quota rule:
> lmtp(8235, eepp68): Debug: Quota rule: root=User quota mailbox=* bytes=0 messages=0
The "bytes=..." value should be different from 0.
http://wiki2.dovecot.org/Quota/Configuration#LDAP states that
user_attrs is used only if you use userdb ldap.
Where is the "userdb" ldap in your doveconf -n output
and where do you get the user information like quota from?

The default is not taken since your LDAP query returns a quota_rule
with an empty bytes= value when the mailquotasize entry is missing.
