Need help with creating an "e-mail read" receipt.
The Zimbra version of webmail doesn't have this option, while the Appsuite version does.
One caveat....you might send a request, but it doesn't necessarily mean the recipient will respond to it.
If you're in the Appsuite version of webmail, with the Compose window open, click on Options on the right side and the at the bottom of the box that opens is Request read receipt. Click on that. YOU won't see anything, but the recipient will.
