    Default Setup Zimbra MTA, LMTP and inbound host names

    Hi,

    could please, someone help me properly setup some parameters in Zimbra server, so to avoid Outlook marking my own messages from my domain and to my domain as spam?

    I have the following setup for mail:

    MX records for ALL my domains:
    IN MX 10 mx1.spamfilter.com
    IN MX 20 mx2.spamfilter.com

    SPAMFILTER servers then forward filtered mail FOR ALL DOMAINS to ZIMBRA hostname, which is:
    zimbra.primarydomain.com

    Inside ZIMBRA I have 10 domains, for example:
    domain1.com
    domain2.com

    etc...


    So, could you please ADD or MODIFY my Zimbra server settings under the following tabs:

    Servers --> zimbra.primarydomain.com --> General Information
    • Display name: zimbra.primarydomain.com
    • Service Host Name: zimbra.primarydomain.com
    • LMTP advertised name: ???
    • LMTP bind address: ???


    Servers --> zimbra.primarydomain.com --> MTA
    • Web mail MTA Hostnames: zimbra.primarydomain.com
    • Relay MTA for external delivery: ???


    Domains --> domain1.com --> General Information
    • Domain name: domain1.com
    • Public service host name: ???
    • Inbound SMTP host name: mx1.spamfilter.com (hmm...either 1 host missing, either wrong setting here)


    Domains --> domain1.com --> Virtual hosts
    • domain1.com
    • zimbra.primarydomain.com

    Let's start with the basics. Please update your forum profile with the output of the following command:

    Code:
    zmcontrol -v
    Next, the output of the following commands (run on the Zimbra server):

    Code:
    cat /etc/hosts
    cat /etc/resolv.conf
    dig yourdomain.com mx
    dig yourdomain.com and
    host `hostname` <-- use that exact command with backticks not single quotes
    I addition to that you have two spam filters but only one of them listed in the Inbound SMTP name, is that correct?

    When you say "Outlook marking my own messages....", do you mean that they're on the LAN or as an external client? Do you mean that it's actually Outlook marking them as spam or the Zimbra server? Is the anti-spam system disabled on the Zimbra server?

    What do the headers from one of these 'spam' messages look like?
    Regards

    Phoenix, thank you for reply!

    DONE!

    Next, the output of the following commands (run on the Zimbra server):

    Code:
    cat /etc/hosts
    cat /etc/resolv.conf
    dig yourdomain.com mx
    dig yourdomain.com 
    host `hostname` <-- use that exact command with backticks not single quotes
    Is this really necessary? I'm not likely into revealing details to public.
    But I am SURE all above settings are OK, since I followed your instructions and configured Zimbra from command line exactly as you told.

    I addition to that you have two spam filters but only one of them listed in the Inbound SMTP name, is that correct?
    Very correct, because the "Inbound SMTP name" field only accepts 1 entry. I was already complying about this

    When you say "Outlook marking my own messages....", do you mean that they're on the LAN or as an external client? Do you mean that it's actually Outlook marking them as spam or the Zimbra server?
    Outlook only marks messages as spam, not Zimbra.

    Is the anti-spam system disabled on the Zimbra server?
    No, it is enabled.

    What do the headers from one of these 'spam' messages look like?
    Here is one example:
    Code:

    My concerns:
    1.) It is weird, that mail sent by IMAP protocol from inside the server, just from one mailbox to another, was marked as SPAM by Outlook. It happens on random mail every few days.

    2.) I am pretty sure most of settings are correct, except maybe those:
    - Inbound SMTP Name: what should it be? The MX records from DNS zone (mx1 and mx2.spamfilter.com) or the Zimbra hostname, which receives mail from SpamFilter (zimbra.primarydomain.com)?
    - Public service host name: what is this for? Is it maybe related to IMAGES in signatures, which require some password to show up in Zimbra?
