Per your feedback, to address the following before the ZCS 6.0.8 cycle we have released a patch to version 6.0.7:
Bug 48296 - Not able to send message with persona from field of external account selected
Bug 48210 - sender name of external account is wrong - zimbraDataSourceName vs zimbraPrefFromDisplay (partial fix till 6.0.8)
Bug 46552 - NumberFormatException when trying to print a virtual/shared conversation
Bug 48146 - Select Addresses dialog no longer pre-populates list from Contacts
Follow Backup and Restore Articles - Zimbra :: Wiki
Then as root on all servers where the zimbra-store package is installed:
tar -xzvf zcs-patch-6.0.7_GA_2476.tgz
-At this time there is no planned full/400mb installer release of build 2476.
-File is 50mb, and you might notice it actually contains 25mb of 6.0.6 patch content as well, but this source has no technical effect. By design zmpatch.pl doesn't install old code on newer versions; we simply didn't prune zmpatch.xml this time.
This was previously released but warrants another mention:
If you need the following fixes to 6.0.7_GA_2470 you will have to use the full installer 6.0.7_GA_2473 available on the download pages.
Bug 48129 - 6.0.7 upgrade failure, Could not bind to port=143
Bug 48095 - Can still query GAL when zimbraFeatureGalEnabled & zimbraFeatureGalAutoCompleteEnabled are disabled
(Order is not important; though if you skip build 2473 and later decide you need the GAL fix, remember to put the 2476 patch on again since the full installer overwrites it.)
