you can have it delivered wherever you want, provided you configure that.

with a pcre sender bcc like this:
/(.*)@example\.com$/      $1 at senderbcc.example.com

postfix will deliver a copy to user at sendrbcc.example.com. Then deliver 
this with

1- dovecot LDA and use Sieve to store the message in the folder you want
2- maildrop and configure it to store the message where you like, or
3- directly with postfix, provided you configure the right 
virtual_mailbox_maps
