Adding imap module to php8.0 under AlmaLinux 9.4

Hello,

I am trying to setup the WordPress Plugin WP Mailster, under a new WordPress installation on an account I have created under Virtualmin (latest version 7.10).

It is telling me I need to install php-imap, but I have been unable to do this by running

yum install php-imap

where I get an error

Error: Unable to find a match: php-imap

Here is the output from php -m , which shows there is no imap module.

I’ve tried googling this, but I’m just getting more confused. Can anyone offer some advice on what I should be doing (or looking at).

Thanks
