Some email accounts are created on my A server and some are created on B . i have to publish one MX record . so now i want that when ever someone send me email on my domain . if accounts is exit on A server it deliver it on that email mailbox . its not found in Server A its automatically goes on server B .

Example :

ali@abc.com is on my B server . so when email comes on ali@abc.com its should be check automatically on server A and then server B and deliver it desired email box.

if any can help on this please let me know.

Basically create all account on one of the two servers. Account that are not really on that server must have zimbraMailTransport set to "smtp:[other_server_ip_or_hostname]:25"
Mail flows to first server. For the local accounts it is delivered, for the other accounts it's routed to the other server
