I need make a migratión from postfix to zimbra.
My client mail is firstname.lastname@example.org
During the migration same user mailbox were in original server (postfix) and other is in the new server zimbra.
Finally whe the migration is finished , all of mailbox are in zimbra.
I think is posible to do it using mailalternate address to do these migration.
inet--> ZIMBRA-----> postfix
email@example.com ------> @uk.example.com
All the mail recibed zimbra, the user migrated to zimbra take mail in zimbra, for the not migrated user , from zimbra redirect mail to @uk.example.com , this mail is in postfix.
Is posible to do it,
