Most likely you need to enable it in your PHP configuration.
In phpinfo, it shows you which ini configuration file PHP loads, and also shows you what additional ini files it loads for configurations. One of those should be the imap.ini file or something similar, and that's where you need to enable the extension. Then make sure you restart your apache server and/or php if running under fpm.
This isn't really a MailWizz issue.
