Re: [Resolved] ERROR: Unable to start TLS: SSL connect attempt failed error:14090086

This is likely due to the Sectigo root CA expiring yesterday: https://www.reddit.com/r/sysadmin/comments/gseefb/reminder_sectigo_root_expires_saturday_morning/ Removing the following line from /etc/ca-certificates.conf does NOT appear to resolve the problem for Zimbra (tested on Ubuntu 18.04): <pre...

Old Comodo Intermediate Certs Expired 30 May 2020.

Some of my customers with multi-year SSL certs found their old Comodo intermediate certs had expired this weekend, even though their commercial SSL certs remained unexpired. This doesn't seem to impact end users while Zimbra is running, but things like the Admin Console will show the big red X's tha...

Re: No puedo acceder al administración web post instalación

Hola,

Necesita usar "https" solamente con el Admin Console. Hay no "redirect".

Saludos,
Mark

P.S. Lo siento, pero yo no puedo hablar Espanol muy bien...

Re: Can't redirect http to https

The MTA side of things should be just fine as is, so the server will continue to receive mail OK, and smtp-auth users (port 587/465) should still be able to send email. But given the current state of this, I’d not worry about what good settings zmprov gs should return and instead I’d focus on runnin...

Re: Zimbra 9 NE, 2FA and mobile app

Zimbra requires you to configure application-specific passwords for each device that does not natively support 2FA.

The 2FA wiki describes the process.

Hope that helps,

Re: Can't redirect http to https

To expand on what Dual Boot has reported, both the Proxy Service and the Mailbox Service need to be configured correctly for proxy to work. And by "correctly" I mean that both Services need to agree on Ports and Protocols. For example: zimbra@mail2:~$ zmprov gs mb18.missioncriticalemail.co...

Re: Can't redirect http to https

Best to set the server running Zimbra's Proxy service to "redirect" mode. As the zimbra user, you can run on the proxy server: zmprov ms `zmhostname` zimbraReverseProxyMailMode redirect zmproxyctl restart Both 80 and 443 need to open in your firewall, but if the zimbraReverseProxyMailMode ...

Re: How I fixed "Host not found, try again" for incomming email ?

Your virtual server is Ubuntu 18.04?

That OS ships with it's own caching DNS server; if you Google "Ubuntu Server 18.04 DNS Netplan" you'll find a lot of articles on how to configure this. You do not need Zimbra's dnscache.

Hope that helps,
Mark

Re: Zimbra 8.8.15 Patch 9 Released

Test upgrades completed OK so I upgraded our BSP hosting farm this evening from Patch 8 to Patch 9 and experienced only one (non-Zimbra) issue: syslogging on the logger host stopped working. A rerun of zmsyslogsetup and a restart of rsyslog just on the logger host put things back to right. Ubuntu Se...

Re: opedkim stopping frequently

zmconfigd is the Zimbra configuration daemon. It rewrites other services' config files when you do things like make changes in the Admin Console, and then zmconfigd will restart the service with the new config files. The log snippet you posted show that zmconfigd is stopping and starting the service...
