I want to create an alias domain and I want that every mailbox of the real domain to be able to receive mail from both the real and alias domains without creating an alias for every user in domain.com.

For example:

real domain: domain.com
alias domain: aliasdomain.com
user: test@domain.com

creation of the alias domain:
zmprov createAliasDomain aliasdomain.com domain.com zimbraMailCatchAllForwardingAddress @domain.com

Now if I send a mail from the outside to test@aliasdomain.com postfix says user unknown in virtual alias table. If I configure an alias for test@domain.com as test@aliasdomain.com all works correctly.

It seems that the creation of the aliasdomain gives the possibility to create the aliasm infact if I try to create the alias in the user management without the zmprov command zimbra gives me an error.

Is there a way to automagically do domain aliasing without create an alias for each filan user? (in plain postfix this is the default behaviour).
