#1

Hello together,

since a while I am running UCS Server with kopano. Everything worked nice, But since saturday I cant get and send email anymore.
I updated on thursday to the newest available versions:
WebApp:
3.3.0.610-25.1
Kopano Core:
8.3.1-35
Z-Push:
2.3.6+0

After uptdate everything was working. But on late friday or saturday it stopped working

In my mail.log following appears:

Please run

ucr set mail/postfix/tls/client/level=none
postfix reload

until we have found a better solution.

A bug fix has been released: http://errata.software-univention.de/ucs/4.2/49.html
Please update and return the UCR variable to its default:

ucr set mail/postfix/tls/client/level=may
postfix reload
univention-upgrade
