Hi everybody! My first post here, so be gentle :P
We have a zimbra 8.0.5_GA_5839.FOSS install with a single domain with about 300 accounts. It is working quite well except for this issue we can't figure out:
some users have configured another account as POP (from same domain), when they write a new message with that identity, requesting read receipt, the message have the disposition-notification-to header half empty like that: " disposition-notification-to: John Smith < >"
When the receiver clicks to answer to the read receipt it gets an error like this:
msg: system failure: error while sending read receipt
name: "ZimbraWebClient - FF26 (Win)",
I also tried setting the "Reply to" filed in the account settings but with no change.
Sending from the main account works fine.
Where should I check ?
