Health Check to inform about a not configured From Mail Address

[SirLouen]

Following the conversation here #60420

I want to summarize in this topic what is really needed:

The problem here is that by default, all emails are being sent with a From: header with an email in the form of wordpress@hostname.

This brought my mind to this report, which is not exactly the same, but the concern here was similar: Poor knowledge by the users leading to some type of trouble (in that ticket, SEO issues, in this ticket, mail delivery problems).

This can lead into two problems:

1. The first is that users without such mailbox enabled could have multiple problems, not only with receiving emails, but with spam checks
2. It's not widely known, and it seems that many people think that the From: email is the same as admin_email option (and many plugins are fostering this behavior.

One of the proposed behavior that seems to resonate well is adding the Site Health recommended improvements. Here an example of how it could look:

Text:

By default, WordPress sends emails from an address like wordpress@localhost. This can sometimes cause delivery issues or make emails appear less professional.r

To customize the sender email, we recommend installing a dedicated plugin or adding the filter hook wp_mail_from

In the last part, it will be linking to this section in the WordPress Administration Handbook that will be talking about Mail (I'm taking care of this, still in progress).

Yes, 100% I did not spot it.
Closing this in favor to the other one.
