Gmail does not detect the reply-to field

Question

I have following settings in my FeedbackMailer.

def notification(feedback)

  from       "[email protected]"
  subject    "Some feedback"
  recipients "[email protected]"
  reply_to   feedback.creator.email
  body({ :feedback => feedback })
  content_type "text/html"
end

I am using [email protected] account to send emails for this application. The emails are delivered perfectly. And when I check the details of the email after receiving it, I see following:

from     "[email protected]"
reply-to "[email protected]"
to       "[email protected]"

Now when I press on the reply button in the gmail interface, the to field should now have the "[email protected]" but it is having "[email protected]". Am I doing something wrong or gmail is?

Answer 1

As the thread Waseem pointed out in a comment indicated.

Gmail ignores the reply-to when the From is one of your configured send-as addresses in gmail. I don't know why.

I took this as a hint and replaced the From email field by the [email protected] and added the same [email protected] as a Reply-to address. Gmail now uses the Reply-to field correctly.

You should check the raw headers of the email instead of just looking on the details, as it is possible that other header affecting the reply function were set by your email server - Sender header, for example. You can see the raw email code using "Show original" function, under the arrow icon in the top-right corner.
