Hi,

today I found a lot of unknown udp-connections where I ask myself what zimbra if doing there.
Here an extract from zimbra.log:

192.168.19.142 is my machine. I am using zimbra webclient (chrome).
Why does zimbra tries to connect to these destinations? There a a lot of more targets in the complete log, tcp-targets too.

Thanks for reply,

Harry
