Code:
Consider this typical Split Domain example:
Your domain is example.com.
Your existing mail infrastructure lives on the host "mail.example.com" (assuming single node install for simplicity, though what we are discussing should also work on multi-node).
Your domain example.com has MX records that point to host "mail.example.com".
Users "foo@example.com" and "bar@example.com" exist in the old system.
You installed Zimbra on the host "zimbra.example.com" and created the domain "example.com" on it also.
You have migrated the mailbox of user "foo@example.com" to the Zimbra system, using one of our migration tools documented elsewhere.
this is not what i mean.
i have cgp as primary server that hold @example.com and the internal mx for that domain is mail.example.com (172.16.4.16).
i have zimbra as secondary server that hold @zimbra.example.com and the internal mx for that domain is mail.zimbra.example.com (172.16.1.21).
i want send email from cgp to zimbra vice versa and not from internet to zimbra.
i already add mail route in primary server to redirect all email with destination *zimbra.example.com to 172.16.1.21.
i want to know, how to accept relay from trusted ip in zimbra?
