Zimbra Open Source 7.2.1 GA.

When I log into the web client from my office (behind a web proxy) and go to the Briefcase and try to open an attachment by double clicking on it, a docx Word document for example, I get

Unable to connect

Firefox can't establish a connection to the server at https://mail.myserver.comhome

On IE the page just never displays anything.

The URL that is given is https://mail.myserver.comhome/myname@myserver.com/Briefcase/Word-doc.docx?ver=1

If I manually fix the URL by removing the "home" part, the document opens fine.


Where is the "home" string being injected into the URL and why only on the web client?

Zimbra Desktop (running on a PC on my the same LAN as the Zimbra server) does not exhibit this behavior, and neither does the web client from the same PC.

I'm stumped.

Thanks for any help
