Hi Mark, Curiosity got the better of me and we are testing this right now. Preheaders are cooked and a nit (don't care as much) but some email can still do preview headers by turning off line height, max width, opacity zero, etc, etc vs display:none which no longer works with P13/P4. Costco and Walm...

Hi JD, Curious if you have had an opportunity to test Patch 4 to see how big of an impact on rendering it actually causes? I have not; I've been conducting Zimbra 3-Day Admin Training this week... All the best, Mark Hi Mark, I have not tested and applied the patch yet. I did test an email by removi...

A few other ideas to help isolate this. Use the debugger (developer mode) built into your browser and watch the network traffic. Choose network tab first and then logout... use the built-in explorer to observe and drill down on those errors. You could also try enabling development mode by adding ?de...

the strange thing is that on another postfix mail server without zimbra that uses the same version of clamAV blocks the same mail that zimbra lets pass. I think it's a weakness of zimbra. We have not found Zimbra to be the problem but it does require that you customize your SA/Virus solution to max...

Just saw the bug fix for inline images that is coming our way. I am a little concerned with the Known issue with this patch that is removing the display attribute . Would like to see some finer granularity with this patch. https://wiki.zimbra.com/wiki/Zimbra_Releases/8.7.11/P13 https://wiki.zimbra.c...

Can you verify that sudo was setup properly? $ ls /etc/sudoers.d 01_zimbra 02_zimbra-core 02_zimbra-ldap 02_zimbra-mta 02_zimbra-proxy 02_zimbra-store where 02_zimbra-mta is: $ cat /etc/sudoers.d/02_zimbra-mta %zimbra ALL=NOPASSWD:/opt/zimbra/common/sbin/postfix %zimbra ALL=NOPASSWD:/opt/zimbra/comm...

I was looking at my 8.7 postinstall notes when I came from 8.6 and saw this: 1) Verify this. zmprov mcf zimbraMtaCommandDirectory /opt/zimbra/common/sbin zmprov mcf zimbraMtaDaemonDirectory /opt/zimbra/common/libexec zmprov mcf zimbraMtaMailqPath /opt/zimbra/common/sbin/mailq zmprov mcf zimbraMtaMan...

It is kind of a mess isn't it. The initial steps document things on the first page. Then it went into a script to help others follow along so there would be less typed mistakes... Eventually, the script wasn't necessary as the acme.sh script evolved and the community developed a deploy hook script t...

FYI, That July 8, 2019 deadline has been pushed back to July 8, 2020 where Letsencrypt was planning on moving away from IdenTrust cross signing. The fix will be trivial on our end next year. Two methods come to mind but probably just replacing the IdenTrust with their X1 cert in the acme.sh zimbra.s...

Probably should provide a usage for others in the future.... Here is an example of one method: su - zimbra ls 2019-05-15 2019-05-21 2019-05-27 2019-06-02 2019-06-08 2019-06-14 2019-06-20 2019-06-26 2019-07-02 df.csv ldap.csv pid sync.csv zmstat.out-20190630.gz 2019-05-16 2019-05-22 2019-05-28 2019-0...
