first of all this is a internal test so no firewalls are invovled.. I have split dns up and running resolving mail.dingit.dk to the local ip of the zimbra server..
the incoming settings works fine...
the outgoing settings I have tried
tls with port 587 says server did not respond 5188.8.131.52 <unknowen[172.16.9
ssl with port 465 says server did not respond 5184.108.40.206 <email@example.com
it works fine using smtp port 25
my network is 172.16.99.0/24 so i suoppose the tls error is either the server that is unknowen or my client..
port test using telnet
I think it may be some MTA thing but im still to new to zimbra to know what to do now?
telnet mail.dingit.dk 587
220 zimbra01.offernet.lan ESMTP Postfix
telnet mail.dingit.dk 465
returns black screen with blinking curser indicating there is a connection
