Around July 2022 - Support for upgraades for CentOS 6 was dropped......

Support for CentOS 7 is supposed to stop at the end of this year.

You can look at upgrading to CentOS 7 from CentOs 6.... There is a way to do it using rsync; without you having to re-install everything and doing a migration.

For some reason Zimbra just does not recognise any wildcard characters in /opt/zimbra/postfix/conf/transportfile nor domain names and the directives given in the guide do not work at all:- http://www.postfix.org/transport.5.html The only way I could get it to work was by entering the actual email ad...

I had a similar issue upgrading to 8.8.15.... It was because you probably customised your postfix configuration at some point... Normal configuration:- su zimbra zmprov gs `hostname` | grep transport zimbraMtaSmtpTransportRateDelay: $default_transport_rate_delay zimbraMtaTransportMaps: proxy:ldap:/o...

Name 3 security fixes that are critical.

The user interface for Zimbra 8 is not as good as Zimbra 7; that's my personal preference.

[SOLVED by https://www.oneday.com.hk/] Sorry - none of the solutions posted on this thread worked for me. The postfix one doesn't work because /opt/zimbra/postfix/conf/main.cf gets overwritten as soon as postfix is re-loaded..... The real config is stored in /opt/zimbra/conf/zmmta.conf - so any upda...

I personally much prefer Zimbra 7 to Zimbra 8.x - there's virtually nothing new in Zimbra 8.x; even the interface and user experience seems to be a step backward. So we are currently looking at ways to get TLS1.2 to work on Zimbra 7. It looks like this directory might be relevant:- /opt/zimbra/java/...

We are on Centos 5.6 (x86_64) Zimbra OSE 7.2.6_GA_2926.RHEL5_64_20131203115905 Postfix - postfix-2.7.10.3z We upgraded our system from 7.0.4 some time ago. All of the external hosts settings were wiped up during the upgrade as expected but we were not able to re-instate the settings as before follow...

I found a rather crude way around the issue which you can try at your own risk. su zimbra zmlocalconfig -e ssl_allow_untrusted_certs=true And then you run the same old commands from this page:- Administration Console and CLI Certificate Tools - Zimbra :: Wiki It did give me some error messages but i...
