Reply To: Easy Reservations overwrites standard wp_mail function?

Before 3.4 there were a bug in wordpress wp_mail function that no HTML emails got send. I wanted to try if it really got fixed but forgot it till now. If so I’ll only redeclare it for <3.4.
I remember a few users using it with the SMTP plugin, but maybe it got updated. You can just delete the redeclaration to test it.
