'Reply-To' email header can be corrupted in WordPress 5.5
Basically, PHPMailer was upgraded from v5.2.27 to v6.1.6 in WP 5.5 and this caused an issue with how RBE was working around how a long reply-to email address could be silently discarded. This technique can now corrupt the 'Reply-To' email header, making it impossible to reply to the correct BuddyPress item by email.
I will backport the fix for the next maintenance release.
