Re: SSL errro for muliple domain while connecting from email client

Again, I believe it is the wrong forum.
It is also not indicated how Outlook and mobile devices are connected (ActiveSync, IMAP, EWS...) and on whether it is Zimbra FOSS or NE.
To me it looks either the wrong domain is chosen or it is a DNS problem.

Re: SSL errro for muliple domain while connecting from email client

I think your problem is not described specific enough to help.
Also it is not installation or upgrade related, so maybe its the wrong forum at all?

Re: Installation Ubuntu 18.04, ZCS9 -> systemd-resolved vs. zimbra-dnscache

Hi Jorge, thank you for your fast reply. Actually I was reading your blog post before. However, my setup differs since this will not be a lab project with use of public DNS and MX records. I would not need dnsmasq since zimbra could look up and find the public DNS records. I thought dnsmasq would ra...

Installation Ubuntu 18.04, ZCS9 -> systemd-resolved vs. zimbra-dnscache

Hi, when installing Zimbra 9 on Ubuntu 18.04, the installation will note a port conflict on port 53. Systemd-resolvered shipping with Ubuntu already listens to the port that and zimbra-dnscache wants to open as well. How would I proceed with that? Kill systemd-resolveded, which will let the host pro...

I reinstalled one instance and can confirm it works now. Seems it was an error on my side - sorry!

Opening Zimbra Web via IP instead of FQDN

Hi, when accessing the Zimbra Webinterface via https://IP instead of the servers https://FQDN nginx will return an error about not reaching the upstream server.

Hi, using 8.8.15.GA.3829.UBUNTU14.64 UBUNTU14_64 FOSS edition, Patch 8.8.15_P1., my self-signed SSL expired.
