Email & ticket auto-responses are sent to "from" address, not to "reply-to" address

Like the subject says, I've tested this with a vacation responder in Zoho Mail and with the 'ticket received' response in Zoho Desk - they both send messages to the "from" address, ignoring the "reply-to" address. This is an issue since requests submitted via a webform will generally be from an email address associated with the company domain but will have reply-to set to the requestor email address, where all replies should go.

Is there a fix for this?
