We have an existing zimbra server in production (Rel 3.1.3_GA) running on FC4. We have installed zimbra ver 6.0.5 on CentOS5.4.

We want to move mailboxes of users in groups to new server. We understand we need to use split domain and try to follow the instruction given in zimbra wiki.As per our understand we do the followings:

Existing production server: 192.168.100.1
New server 192.168.100.50
domain company.com

We have migrated one user test@mycompany.com to new server.

We have run the following command in existing server (Primary, 192.168.100.1)
a. zmprov ma test@mycompany.com zimbraMailTransport smtp:192.168.100.50:25
b. zmprov ma test@mycompany.com zimbraMailTransport lmtp:192.168.100.50:7025

We have run the following command in new server (Secondary, 192.168.100.50)
a. zmprov md mycompany.com zimbraMailCatchAllAddress @mycompany.com
b. zmprov md mycompany.com zimbraMailCatchAllForwardingAddress @mycompany.com
c. zmprov md mycompany.com zimbraMailTransport smtp:mail.mycompany.com
d. zmprov mcf zimbraMtaRelayHost 192.168.100.1
e. zmprov mcf zimbraMtaDnsLookupsEnabled FALSE


Now while trying to send a mail to test@mycompany.com, we are getting the following smtp error:
host 192.168.100.50[192.168.100.50] refused to talk to me: 502 5.5.2 Error: command not recognized

In the zimbra log of existing server we noticed:
Jun 2 14:17:11 postfix/lmtp[23248]: 3D46F19912BF: to=<test@mycompany.com>, relay=192.168.100.50[192.168.100.50], delay=0, status=bounced (host 192.168.100.50[192.168.100.50] refused to talk to me: 502 5.5.2 Error: command not recognized)

In the zimbra log of new server (192.168.100.50) we noticed:

Jun 2 15:54:07 ms2 zmmailboxdmgr[10607]: status OK

Jun 2 15:55:28 ms2 zmmailboxdmgr[11905]: status requested
Jun 2 15:55:28 ms2 zmmailboxdmgr[11905]: status OK

We are able to send mail from test@mycompnay.com.

Is there anything related to the command not supported by the version of zimbra? Are we dong something wrong in command?

Any help will be highly appreciated.
