    Default [SOLVED] Setting MTA hostname to public name for host which is on private network...

    Is it possible to set the hostname of the Zimbra MTA such that when the server sends mail outbound HELO/EHLO does not reveal the private hostname?

    When I send mail now, the mail bounces on some mail servers (which are configured correctly to block bogus hostname/PTR pairs):

    550 5.7.1 We do not accept mail from dynamic-IP hosts or generic/machine-generated hostnames - you must get a custom reverse-DNS name from your ISP for your host: mail.myco.lan

    Thanks.
