Domain rewrite and Mail Receive trouble

[newtozim]

Hi everybody,

i need some help, i'm installing a zimbra 7 NE on 2 server 1 for the LDAP and 1 for the Store.
I want to keep, my old server as primary.
My domain is my.domain.com, i've even created an alias domain.com.

The old server ( should be a qmail ) have 2 smtp : 1 outgoing - 1 incoming .
Now first of all, i've set as Secondary Zimbra, as indicated on Split Domain, and for smtp i've set the smtp-out.

I'm able to send mail as my.domain.com, but i'd like to send it like domain.com, what should i change to make it happen?

Second I can't receive the mail in my.domain.com users account, the user seems not reconized by the server,I've created the user in both. any idea about what to change to receive the mail?

Thanks 4 the help

Read the Split Domain article for details.

I found how to masquerade the domain following this wiki :

Managing Domains - Zimbra :: Wiki

zmprov md domain.com zimbraMailCatchAllAddress @domain.com zimbraMailCatchAllCanonicalAddress @example.com

I'm still not able to send mail between the domain user, even if they are in my zimbra server, i can't see the GAL.

And keep doesn't receive the mail.... even if i've set Zimbra as secondary following the suggested link of Split Domain.
