Related to the ticket #41750

We finally have PHPMailer 6 in WordPress core. The PHPMailer author noticed that there are some improvements in the way we use PHPMailer.

if you're setting content-type headers and boundaries via addCustomHeader, you're using PHPMailer wrong! (

I would like to request comments and thoughts on taking a good look at how we use PHPMailer. I suspect these outdated patterns were used when WordPress had PHPMailer 5.x series. Now that we use PHPMailer 6, we can review and improve how we use it.

PHPMailer 6 upgrade milestone is WordPress 5.5. It would be great if we ship these changes with same version.
