ZCS 8.6 with Squid HTTPS Reverse Proxy - Issues after ZCS Upgrade

Hi j2b, I'm not sure what it is to be honest but I don't think it's CA validation. It's perfect internally when connecting to the internal IP. Also it's perfect from External when using NAT. I've had to use NAT as a workaround so it's not that great of a deal at the momen...

snmpwalk dont work's with zimbra application

From what I can remember Zimbra SNMP is pretty basic. It can't be polled like a conventional SNMP device. Instead it can only be configured to send SNMP traps when a service is stopped or fails etc. zmlocalconfig | grep -i snmp should return something like this: snmp_notify = yes snmp_trap_host ...

missing features in 8.5.1

1. It does seem that the option to disable bubbles is no longer available. 2. Go to Preferences --> Mail --> Composing Messages. You can turn off the headers there. 3. There seems to be no way to automatically show the BCC field. The only way to do it is by going through the steps you already outlin...

How to configure Zimbra behind an Hardware Firewall

That looks okay. All you have to do is test it. Send a mail to yourself from a gmail account or other external mail account. Keep an eye on /var/log/zimbra.log to see if mail is arriving at the MTA. Also make sure DNS works correctly on your Zimbra Server. for example ping google.com from the comman...

ZCS 8.6 with Squid HTTPS Reverse Proxy - Issues after ZCS Upgrade

Hi Ram, Yes, SSL 3 is disabled. It's interesting because as a workaround I have used NAT to port 443 to be able to access the web client. What makes this interesting is that if I connect from the internal network to the Web Client using the latest version of Chrome I can see that the connection ...

How to configure Zimbra behind an Hardware Firewall

Hi Anupam,



You will have to change the IP address of your Zimbra server to one that is available in your internal network.

How to configure Zimbra behind an Hardware Firewall

You can assign your public IP address to your firewall and then configure NAT on the firewall to forward ports 25 and 443 to the internal IP address of your Zimbra server.



This should allow your ZCS to receive mail and allow clients to access the web client using HTTPS.

Not able to send mail from my co mailserver

You have a DNS issue. Your MTA cannot find any MX records so it does not know where to send e-mail to. Check your /etc/resolv.conf You might need to specify a proper DNS server there. But if you see the words "Network Manager" anywhere there it will be a bit more complicated. One of the me...

ZCS 8.6 with Squid HTTPS Reverse Proxy - Issues after ZCS Upgrade

Greetings! Having upgraded yesterday to ZCS 8.6 I'm having issues connecting to ZCS Web Client through a reverse proxy that was working fine before. Squid version is 3.3.10. Squid is configured as an HTTPS reverse proxy. The SSL certificate that it uses is the same wildcard certificate as the on...
