 Good morning,

 I am experiencing problems when displaying order confirmation emails and
 contact forms from multiple WordPress websites.

 This code is displayed first in the emails:
 Content-Type: text/html; charset=UTF-8

 I've already been looking into what could be causing it. There it was
 indicated that it was due to the PHP Mailer version of WordPress. Could it
 be that the PHP Mailer update is not current with the new version (6.4.3)
 of WordPress?

 Yours sincerely,
 Diana

 Hi and welcome to WordPress Core Trac!

 > There it was indicated

 Could you share a link to the explanation that this issue is related to
 PHPMailer?

 If PHPMailer 6.8.1 is the cause, it could be resolved soon. WordPress 6.5,
 expected to be available later this month, will have the latest PHPMailer
 6.9.1 (#59966).

 I have seen a different issue with `Content-Type` headers in an old
 version of an SMTP plugin. If you have an SMTP-related plugin, I think
 that is another possible cause.
