[Mime] Improve or document In-Reply-To and References headers #45097
Description
Description
As @micheh reports, since #44732 it's more complicated to add an In-Reply-To or References header, since you have to take care of the brackets <...> yourself, see #44732 (comment)
- I could try to create a PR for something like
->addRelaxedIdHeader()that adds the brackets, but doesn't validate the content - Or I could just document the status-quo and tell people to add the brackets themselves: https://symfony.com/doc/current/mailer.html#message-headers
What do you think?
