Heya Jeff,As far as I am aware, this isn't something you need to "enable" on your server. It's handled by your email client. I haven't enabled anything special on my server (tho it is a RaQ3) and my test return receipt came through fine.
Best, Kam.
I want to allow users to request delivery receipts (i.e. through the Return-Receipt-To: header), but I'm not sure how to do it. I'm pretty sure it has something to do with the /etc/mail/sendmail.cf file. Can someone give me a few instructions on what to change and where? I haven't tried anything yet because I don't want to mess anything up. Thank you, Jeff
