Mail server limit to 50 accounts

Hello
I noticed a new limit of 50 email users after the latest update.

problem solved. i found how to change the limit value at the mail settings

can you help me and show me how ?

It can be modified in the Mail Server interface. Note that the plug-in and aapanel need to be upgraded to the latest version.

both are in the latest version, but still can't find the option for the existing domain!
