    Default outlook gives errror 554.5.7.1 when doing the send check using imap

    I all..

    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 554.5.7.1 <unknowen[172.16.9
    ssl with port 465 says server did not respond 554.5.7.1 <casper@dingit.dk
    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

    Code:
    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
    I think it may be some MTA thing but im still to new to zimbra to know what to do now?

    THANKS

    I can add to the case that it seems it only when im outside the local network that i CAN'T send emails... i don't know if this helps?

    There are plenty of descriptions of this error message on the internet, try some of the solutions in those.
