This issue comes up every now and then so thought I'd post the underlying problem and solution...
The attribute zimbraProxyAllowedDomains appears multiple times in each COS (Class of Service). Based on a COS creation template, the attributes are added to a COS at the time the COS is created.
Periodically, Zimbra releases a new zimlet or some other functionality that expands the number of zimbraProxyAllowedDomains in newly-created COS's. But, existing COS's never get updated automatically by Zimbra, even during Zimbra upgrades.
If the attribute is missing, you get the OP's Jetty error.
As of Zimbra 7.1.3, here is the list of zimbraProxyAllowedDomains for a newly-created COS.
Code:
zimbraProxyAllowedDomains: *.googleusercontent.com
zimbraProxyAllowedDomains: api.tr.im
zimbraProxyAllowedDomains: *.smartsheet.com
zimbraProxyAllowedDomains: api.bit.ly
zimbraProxyAllowedDomains: *.tweetmeme.com
zimbraProxyAllowedDomains: *.yimg.com
zimbraProxyAllowedDomains: *.joedeveloper.net
zimbraProxyAllowedDomains: localhost
zimbraProxyAllowedDomains: *.broadsoft.*
zimbraProxyAllowedDomains: *.salesforce.com
zimbraProxyAllowedDomains: twitter.com
zimbraProxyAllowedDomains: *.calcxml.com

zimbraProxyAllowedDomains: *.zimbra.com
zimbraProxyAllowedDomains: *.maxmind.com
zimbraProxyAllowedDomains: *.xdp.broadsoft.com
zimbraProxyAllowedDomains: *.csgnetwork.com
Any that are missing from your existing COS's can be added via the command stated earlier in this thread.
Hope that helps,
Mark
