    Exclamation [SOLVED] NEED HELP - Changing Postfix Master & Main Config for DynDNS Services

    I finally jumped in and made my evaluation install. Problem now is - no mail is flowing - I need to solve this quickly. Read On.

    I need to change both Zimbra Postfix Main cf and Master cf files so I can receive and relay mail to DynDNS. Master.cf and Main.cf are in two places in Zimbra and the Master is write protected. How can I make the following changes without breaking Zimbra? I considered changing the ownership of the files and hacking. But maybe there is a better "Zimbra" way. Suggestions appreciated.

    In my previous Postfix Main.cf I set:
    relayhost = outbound.mailhop.org:2525
    #To allow relay to DynDNS on port 2525 (ISP blocks 25)

    smtp_sasl_auth_enable = yes
    smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
    #To authenticate with DynDNS

    On the Master.cf I set:
    2525 inet n - n - - smtpd
    #To listen on port 2525 of incoming mail from DynDNS

    Default

    Solved - found out what to edit "Master.cf.in."
    Note: DYnDNS authenication does not use TLS.. SSL only
    Set your clients to use SSL when relaying out to this service via Zimbra
