I upgraded from 4.5.5 saturday night and ever since, when my users send a message through the zimbra web client, the "Sent By" only shows their email address instead of showing their name and email address.
I've attached a screenshot of what I'm talking about. The "To" is always shown correctly, but never the sent from. And if I go into the Sent Items box of the person who sent it, it also only shows the email with no name.
However, when I mouse over the email address listed (my own in this example), it shows the correct info from my Contact list.
Any help is appreciated.
