Re: How to white list domains when reject_unknown_helo_hostname or reject_invalid_helo_hostname is enabled

I have updated my original post so that it is clear. The WIKI is wrong.

You can follow the instructions in the upper part of the post get whitelisting working. Verified that it works with 8.7.

Re: dkim zimbra 8.7

Anyone who is reading this, please note that the instructions above are not the best method for adding a DKIM. Don't edit this file because it is zimbra core and you will lose your changes on the next zimbra upgrade anyway. /opt/zimbra/libexec/zmdkimkeyutil Please look at the Bug report that Jorge l...

Re: How to add DKIM record on zimbra 8.7

Editing a core Zimbra file doesn't sound like a good idea and you will probably lose the change when you next upgrade to the latest version. Don't edit this as suggested above. /opt/zimbra/libexec/zmdkimkeyutil Please look at the bug report. Specifically comments 8, 9, and 11. https://bugzilla.zimbr...

Re: how to whitelist a domain no matter what?

I was actually able to resolve the particular issue I was having. I first turned off: reject_unknown_client_hostname I then added not only the domain name, but the IP address of the server that was trying to send to us in /opt/zimbra/conf/postfix_blacklist We had previously added the domain name, bu...

Re: Gmail response to a zimbra appointment invitation does nothing.

How are you creating the invites? Note that whatever creates the invite should ensure that the ATTENDEE record in the invite corresponding to the GMail user has RSVP=TRUE That is what tells mail systems receiving invites that a response is desired. Our server is 8.6. We are using a web browser to c...

Hello, I have an existing Zimbra 8.6 server on which users have historically not used the calendar function. I have one user who wants to interact with external parties and create appointments in their zimbra calendar to keep track of meetings. When we send an appointment invitation to an Exchange o...

Re: Zimbra Collaboration 8.7.x and Ubuntu OS update corrupts/removes Zimbra installation

I have a side question. We have a few Ubuntu 14.04.5 LTS servers with Zimbra 8.6 (Release 8.6.0.GA.1153.UBUNTU14.64 UBUNTU14_64 FOSS edition, Patch 8.6.0_P6.) I'm wondering if it is recommended to upgrade Ubuntu first and then Zimbra to 8.7, or if it is recommended to upgrade zimbra to 8.7 and stay ...
