Warning: you already have Mail Domain settings and mailboxes for users present in your {0}Mail{1} module. Changing the settings here you realize that these changes can affect their work and result in mail server failure. If you completely moved the {0}Mail Server{1} to another computer and/or changed database access credentials, just update the {0}Mail Server IP{1} and/or credentials here. If you created a new {0}Mail Server{1} and want to connect it, you need to delete the old data at the {2}Mail Server page{3} first.
