We recently upgraded to 4.6.3, and now the reply-to email address in CiviMail e-mails defaults to the system e-mail, not the From sender e-mail address, as previously. I could not duplicate on the demo site (at http://d46.demo.civicrm.org ), perhaps because the demo site is running 4.6.5.
A real bummer, any help fixing appreciated. Was this a 4.6.3 bug that has now been fixed in 4.6.5?
Thanks.
