Trying to troubleshoot all aspects of this issue.
Zimbra Web Client can load embedded images in any browser except Firefox ESR 17.0.4 - 17.0.7 Mac and Windows (browsers I'm testing against). Works in Chrome, Safari, and iOS.
I have played around with enabling/disabling "Display pictures automatically in HTML Email" yet no joy.
Any idea where continue troubleshooting further settings changes?
Any help is greatly appreciated.
