Re: Certificate Question

There are a number of ways to prove ownership of the domain. If you can receive email for postmaster@ or hostmaster@ you should be fine. https://wiki.zimbra.com/wiki/Administration_Console_and_CLI_Certificate_Tools I like the Thawte ssl123, but there are many options at different price points. I hav...

Re: Certificate Question

The best thing to do would be to purchase and install a certificate from a certificate authority. That way there will be a chain of trust, and you will not get that error on any common web browsers.

Re: How to get IP of user trying to connect to web interface?

I wrote a monitoring daemon, zlockoutd, to send the admin an alert when there is a lockout. You can get it from here. https://github.com/howanitz/zimbra_lockoutd Additionally, I have something like the following running on a cronjob - I also run it manually if there is a lockout to find where the di...

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

I am waiting on upgrading (the paid NE) until things stabilize more. I wish issues of this order would get email alerts to paying customers.

Re: zmbackup schedule

The recent security updates for Ubuntu wants to replace the /etc/sudoers file. If you allow it to do so, Zimbra will not run properly after the required reboot. You will get errors and prompts asking you for the zimbra password when running 'zmcontrol status'. You should back up /etc/sudoers first, ...

Re: Large amount of emails sent during the night (possible spam)

I do run it as a cron job, but if you cannot run it manually, it will not run as a cron job either.

Did you change all the "example.com" text?

Did you make your file executable with chmod?

Did you remember to include the path when running it?
