PHP IMAP Extension, PHP XML Extension and PHP XML-DOM Extension

mqn

during installation, the first time access appears like this, what does that red cross mean for me?

The first three red X's are PHP extensions that you need to enable in your php.ini to enable them.
The first is required to fetch email to make emails into tickets.
The second is required for API stuff.
The third is for HTML email processing. (If you want to receive HTML emails)

The fourth X is caching. You do not need this for anything other than possibly speeding up performance of your site.

This question has been asked in multiple places. I'm running v1.18.2 and it still asks for php-imap yet other places in the forums, it's not required any more. Oracle Linux 9, Red Hat Linux 9, Alma Linux 9, Rocky Linux 9 do not have php-imap available. What is the correct answer?
