Update 1 After doing a bit of digging on that DNS error I think I found the problem on my end. While my server does have DNS servers configured and working properly they were not listed in /etc/resolve.conf. I re-configured things so Network Manager put my DNS servers into /etc/resolve.conf, restar...

We have the same problem, have you found a solution?

Nope!

Just an FYI this issue still exists in 8.7.1.

I upgraded from 8.7.0 to 8.7.1 and got the same error.

Manually running "/opt/zimbra/libexec/zmsetup.pl" as root after the upgrade failed still works and finishes the failed upgrade.

I've updated the info in my bug.

This issue appears to be resolved for me after updating to the latest OpenLDAP packages that Zimbra published for 8.7. In my case I run CentOS 6 so I performed a 'yum update', got the new OpenLDAP packages and then re-ran the Zimbra setup (/opt/zimbra/libexec/zmsetup.pl) as root. It appeared to iden...

Well much like anything complicated involving Zimbra Open Source Edition we're probably not going to get an answer to this issue at this point.

I've submitted a bug report: https://bugzilla.zimbra.com/show_bug.cgi?id=106546

After some digging I think this issue might be related to Zimbra 8.7 putting more weight on bad/missing DMARC compared to 8.6.

Did 8.7 change the way it handles DMARC on incoming e-mail compared to 8.6?

Specifically I see DMARC_FAIL_REJECT in the e-mail headers bumping the spam rating pretty high.

I assume Zimbra learns over time and improves it's spam filtering based on items you whitelist, blacklist and general e-mails you send/receive. Since upgrading to 8.7 (from 8.6) Zimbra is pretty much only catching my legitimate e-mail now as spam. Is there anyway to "reset" the spam filter...

Performed an upgrade from 8.6 to 8.7 on CentOS 6 64-bit (after installing 8.6 memcache and proxy first). This is the output from my installer: root@micro.fizi.ca:/temp/zcs-8.7.0_GA_1659.RHEL6_64.20160628192545# ./install.sh Operations logged to /tmp/install.log.609qSkJq Checking for existing install...

Release 8.6.0_GA_1153.RHEL6_64_20141215151155 RHEL6_64 FOSS edition, Patch 8.6.0_P1.

I ended up building my own Antispam gateway on a DigitalOcean VM and using it for relaying to/from my home server.

This worked around the problem of my IPS relay blocking me for sending spammy NDRs.
