Well you are going to have to explain your sendmail and procmail setup then. procmail does not know anything about creating multiple mailboxes under a single system account. You have to tell it where to place things, that is, you need to create directory structure yourself and the appropriate procmailrc files. Likewise, you are going to have to build the procmail command line in postfix if you are really using procmail in a virtual mail setup with sendmail. Are you really using one system account to store multiple mailboxes or are you just using sendmail's virtuser table?
