Hello, I'm having some problems configuring a relay on zimbra.

-> I've created a domain called first.com and another second.com
-> filled the users with the zmprov commands
-> while were waiting for a complete migration of first.com, i've configure the domain to relay to the old postfix with the folloing commands :

zmprov md first.com zimbraMailCatchAllAddress @first.com
zmprov md first.com zimbraMailCatchAllForwardingAddress @first.com
zmprov md first.com zimbraMailTransport relayld-postfix.com

When a user user@second.com send a mail to a user@first.com, the mail stay in the zimbra server and it's not relayed by the zimbra.

When i look in zimbra.log, it's say relay=127.0.0.1 or the name of the server

zimbra.log :
