    Hi All,

    I have 2 email server Zimbra with the following information :
    Code:
    domain : example.com
    server1 (old): mail.example.com - IP 192.168.100.1
    server2 (new): mail.example.com - IP 192.168.100.2
    i am newly migrate from old zimbra to new Zimbra mail server with same schema (domain, hostname). Old email server still use to other purpose and it have 1 account with name user1@example.com. New email server has been used as production server.

    I want all email with recipient user1@example.com will forward to old email server with change transport smtp:192.168.100.1:25. But i get output error like this
    Code:
    <user1@example.com>: mail for 192.168.100.1:25 loops back to myself
    any idea with my problem?
    Best Regards,

    Hi Ahmad,

    I don't know why do you need this ...but your problem is the very same hostname used by each postfix istances, so you can try to change the postfix helo value on one of istances (smtp_helo_name).
    Code:
    zmlocalconfig -e postfix_smtp_helo_name=mailnew.example.com
    Depending of your zimbra version, if you have, this property should be supported without any other changes.
    Check zmconfigd.cf/zmmta.cf file if you find a line like:
    Code:
    POSTCONF smtp_helo_name				LOCAL postfix_smtp_helo_name
    Please pay attention that this change can have some implication on your external mail delivery, like DNS and reverse-DNS checks made by all recipient mailservers.

    Have a nice day.
