Several configuration parameters of the mailcow UI can be changed by creating a file data/web/inc/vars.local.inc.php which overrides defaults settings found in data/web/inc/vars.inc.php.

The local configuration file is persistent over updates of mailcow. Try not to change values inside data/web/inc/vars.inc.php, but use them as template for the local override.

mailcow UI configuration parameters can be to...

• ...change the default language*
• ...change the default bootstrap theme
• ...set a password complexity regex
• ...add mailcow app buttons to the login screen
• ...set a pagination trigger
• ...set action after submitting forms (stay in form, return to previous page)

* To change SOGos default language, you will need to edit data/conf/sogo/sogo.conf and replace "English" by your preferred language.
