Don't know if this has been discovered yet (I don't see it in searching for it) so here it is.
I have noticed that the email program does not respect the reply to address provided. For example, when I receive an email from a listing I have on Kijiji, the email comes from
post@kijiji.ca, but the reply to field is the person who filled the form out. If I reply to the email in Outlook, or GMail, the reply goes to the address in the reply to field. If I reply using my Vox, it goes to
post@kijiji.ca and the person trying to communicate with me never gets my email.
