change messages count limit

[Luca2186]

Hi,
I noticed that each mailbox created in cwp can contain a maximum of 10000 messages.
Once this limit is exceeded, the mailbox results full regardless of the space occupied by the messages on the disk.
I can also see this limit from roundcube by clicking on the icon of the used space .
I can't figure out how to change or remove this limit.
Please, could you help me?

I found that the value can be changed into the dovecot user_query in the dovecot-mysql.conf file
