I'm a bit confused. The user that it can't be delivered to should be "<a@wibyhere.net>". This is a pretty standard bounce message.

If you want more details yourself about why its not delivering your better off checking /var/log/maillog and /opt/zimbra/log/mailbox.log

Yes! I am having the same problem!

Aaron: the problem is that the bounce message is not providing a useful error, at the end it says:

"<user@domain.com>: domain.com"

Normally Postfix gives an error message like:

"<user@domain.com>: Recipient address rejected: User unknown"

The uninformative error message confuses senders that have made a basic error like misspeeling the recipient address.

Is there any way to get Zimbra to provide a more informative bounce message for mail to an unknown user?

As mentioned above, that's a standard bounce message. The error states what actually happened, if the destination email was incorrect the recipient server will bounce the mail back to you.

Phoenix: that is absolutely not a standard bounce message -- I have managed many Postfix installs and the bounce message nearly always provides useful context for the sender. It may be less than ideal, like "recipient unknown in virtual address table", but it's still better than "<domainname>".

Then if you wish to change it follow any of the tutorials on the internet, search for "+postfix +"bounce message" +change" and you should find something that may help.
