    Default DKIM Signature

    Did anyone tried using DKIM signature or Domain key through Zimbra and dkim-filter.?

    I'm sure people have used it but you'd be far better giving a description of your problem and what you've done with DKIM and what your configuration is.

    I followed this forum as zimbra functions on postfix.

    Quick And Easy Setup For DomainKeys Using Ubuntu, Postfix And Dkim-Filter | HowtoForge - Linux Howtos and Tutorials

    I tested my domain key selector at this page, and it worked fine.
    postalmail._domainkey.americanmutuallons.com

    But i could not let it run DKIM. I am checking at this website for domainkey information on my email.

    I don't even know where to find the error logs. my master.cf includes this from: DomainKeys filter for Postfix

    /etc/postfix/master.cf:

    #
    # modify the default submission service to specify a content filter
    # and restrict it to local clients and SASL authenticated clients only
    #
    submission inet n - n - - smtpd
    -o smtpd_etrn_restrictions=reject
    -o smtpd_sasl_auth_enable=yes
    -o content_filter=dksign:[127.0.0.1]:10027
    -o receive_override_options=no_address_mappings
    -o smtpd_recipient_restrictions=permit_mynetworks,per mit_sasl_authenticated,reject

    #
    # specify the location of the DomainKeys signing filter
    #
    dksign unix - - n - 10 smtp
    -o smtp_send_xforward_command=yes
    -o smtp_discard_ehlo_keywords=8bitmime

    #
    # service for accepting messages FROM the DomainKeys signing filter
    #
    127.0.0.1:10028 inet n - n - 10 smtpd
    -o content_filter=
    -o receive_override_options=no_unknown_recipient_chec ks,no_header_body_checks
    -o smtpd_helo_restrictions=
    -o smtpd_client_restrictions=
    -o smtpd_sender_restrictions=
    -o smtpd_recipient_restrictions=permit_mynetworks,rej ect
    -o mynetworks=127.0.0.0/8
    -o smtpd_authorized_xforward_hosts=127.0.0.0/8

    Execute postfix reload for Postfix to respond to changes in /etc/postfix/master.cf.
