Hi Steve,
This is in the pipelines, as they have only recently added the read receipt, which works beautifully with the new ZCO.
I don't see how this can be a show stopper though, as a read receipt is even more valuable than a delivery receipt... Also, a delivery receipt doesn't guarantee that the message actually reached the recipients' mailbox, only a server that is enabled to respond. Many servers block delivery/read receipts in any case...
Oh, well, I suppose some clients are quite stuck in their ways, but I would try to convince them another way. Zimbra really does what clients need and is constantly being improved. I'm sure delivery receipts will be available one of these days.
Best of luck. |
