Well i tried to changed or fix issue or directory while receiving a new email, which i want to make the location to whatever the mail to be in that respective user's home dir mail folder.

in postfix main.cnf
home_mailbox = Maildir/
mail_location = maildir:/home/%u/mail
Now after i restarted both postfix and dovecot but still all the new emails received in 'firstname.lastname@example.org' being stored in
