    Question SMTP relay no authentication


    Firstly I apologize for the long post. I am new to linux and zimbra so some of my inquiries may seem retarded

    I have a question regarding setting up smarthost for my zimbra server
    running on Debian 6

    I need to set up zimbra so it relays to an anti-spam hardware (transparent brigde) which requires no authentication whatsoever (it is also running postfix).
    Thing is, I set up the "Relay MTA for external delivery" to the IP address of the device, save the settings, but nothing is changed - e.g. I send email from the zimbra webmail to an external address and within the headers I see it was not relayed.
    I tried using another mail server, which actually has a proper DNS name etc - still the same result - as if the setting is not changed.
    I tried configuring Zimbra from the command prompt with "zmprov ms zimbraMtaRelayHost", however this has not worked as well.
    I don't know whether this is related, but I got the following error in the daily mail-report:
    postfix-script (total: 15)
    5 not owned by root: /opt/zimbra/postfix-
    5 not owned by root: /opt/zimbra/postfix-
    5 not owned by root: /opt/zimbra/postfix-

    Fatal Errors
    postfix-script (total: 1)
    1 the Postfix mail system is not running
    postqueue (total: 10)
    10 Queue report unavailable - mail system is down

    I am looking forward to any help you can provide

    Hi Carl!

    Thank you for your reply.

    At the time I did zmcontrol restart and this did not change a thing.
    However the next day it just started working (smarthost configured to an IP address) all by itself.
    I have no explanation to this lol.
