Add a wp_mail() check to Site Health Info

[lakshmananphp]

Check whether the site can send emails via wp_mail() and add the status information to Site Health.

This would help debug email deliverability.

This was discussed during a bug scrub. When site cannot send email, I am considering it as a critical issue and Site Health holds no information about this. I believe that there are two options - to send generic email so site admin while checking this ability or to store the information about failures if they are happening. This issue can be temporary or permanent so, by having this information site owner can make some reasonable decision to use a plugin, to change setting or adjust hosting permissions.

I am removing version because this is true for all previous WP versions.

To test email deliverables properly, you need to actually send an email; having Site Health do this automatically will quite often be considered spam, and is unfortunately not something that WordPress can do.

That said, the Health Check plugin has this specific tool available, and anyone needing to test their emails can use the plugin, as the testing is then caused by a users direct action.

Due to the above mentioned concerns and restrictions, I'm going to recommend this be closed as wontfix.

As @Clorith has suggested, to test email you have to actually send the email and doing this automatically is not an option which means that this must be closed as wontfix

But on the other side, we could add some suggestions to improve deliverability as a new Health Check category, such as the idea proposed here #62129, we are currently discussing.

For this reason, we should continue the conversation there and focus efforts on this, which can be achievable. Closing this and adding it to continue in this other thread.

While #62129 is similar, I wouldn't say this is a duplicate. The former focuses on the From: email being used where as this one suggests confirming the result of actually sending an email.
