Current issues in ZCS 8.5
Current (Known) Issues in ZCS 8.5 Build 3040
- Please note: Build 3040 was the first build released as ZCS 8.5. Then, two serious bugs were found:
- Build 3042 was then built and released - this is the build available from the download locations today:
- Network Edition: http://www.zimbra.com/downloads/zimbra-collaboration
- Open-Source Edition: http://www.zimbra.com/downloads/zimbra-collaboration-open-source
- One can see the build number in the download package, e.g., zcs-NETWORK-8.5.0_GA_3042.RHEL7_64.20140828204423.tgz
- ZCS 8.5 Patch 1 was also released to fix the above issues:
- If you are running Build 3040, you should definitely patch. If you are running Build 3042, then you don't need the patch (although it won't hurt anything to install the Patch 1 on top of 8.5 Build 3042).
- ZCS 8.5 Patch 2 is being developed and is planned for release in a couple weeks, once ready.

Connections from proxy to mailbox are always sent over https regardless of zimbraReverseProxySSLToUpstreamEnabled setting. In case your mailstore's are configured to listen only on http, then users will get 502 errors.
Set zimbraMailMode to "both" on mailstores.

System account for spam/non-spam training should disable spam check
Spam check is enabled for spam/non-spam accounts. This causes any spam/non-spam marked emails to get filed into Junk folder of spam/ham accounts. zmtrainsa extracts messages from Inbox only of spam/ham accounts, resulting in no training of emails in Junk folder.
On the MTA, as the ZIMBRA user:
REPLACE line 116 with:
%%comment VAR:!zimbraAmavisOriginatingBypassSA%%bypass_spam_checks_maps => , # don't spam-check internal mail if desired:
Generate CSR fields are not added to CSR
Generating CSR from admin console, fields "C=, ST=, L=, O=, OU=" are not added to the CSR. Generated CSR always contains these values.

This is fixed in patch1 and in the build 3042.

Please check if your /etc/hosts file has a line for both "127.0.0.1" and "::1", and if so and you're not using IPv6, please comment out the "::1" line and try again.
Postconf all keys.
Handy to know all postfix config keys that are added in 8.5. In some cases, postix LC keys are not being applied to postfix, because those are moved to ldap database. This list will help to know those keys.
