Now that we can use RT personalization for Subject and Email From Name (and From Address in regular mailings) it would be great to enable this for From Address within programs. When trying to use an RT field in the From Address within a configured mailing in a program I get a "Not a valid Email Address" error as the validation is looking for an email format. Not sure if just the validation needs updating or if the underlying system needs to be modified to enable RT values for From Address but this is a big piece we were hoping for when RT personalization was enabled.
