SQL user_query quota_rule for *:messages=

[James]

Hello,

dovecot.conf sets the system default quota for storage and message count:
plugin {
   ...
  quota_rule = *:storage=1G
  quota_rule2 = *:messages=10000
   ...
}

This quota_rule for the storage is overridden by an SQL user_query in 
dovecot-sql.conf:

user_query = "SELECT ... '*:storage=' || maxstorage || 'M'  AS 
userdb_quota_rule, ...;"

Is it possible to override the message count limit with an SQL 
user_query (and password_query)?




I tried returning userdb_quota_rule2 in the SQL but it did not work. 
"SELECT ... '*:messages=' || maxcount AS userdb_quota_rule2 ...;"
