I have also the virtual_alias_domains which include: bbb.com

I know how to forward x@bbb.com to y@aaa.com by setting up the file "virtual_alias_maps": x@bbb.com y@aaa.com

But, how can I setup virtual_mailbox_maps (if I name this correctly)? for example, 111@aaa.com forwards to 222@aaa.com.

These are postfix questions posted to a dovecot mailing list.

virtual_mailbox_domains = Where you list domains that postfix is final destination for. virtual_mailbox_maps = Is where you list virtual addresses and the mbox/maildir path for the virtual delivery agent. virtual_alias_maps = Is where you list aliases such as x@bbb.com -> y@aaa.com and 111@aaa.com -> 222@aaa.com

An alias is an alias regardless if its to a local or remote address.
