Now any new mail injected on the system will go to qmail. Draining sendmail's queue Check that sendmail's mail queue is empty.
Users can always override the delivery instructions for their own addresses, via .qmail files.
Maildir delivery is reliable, unlike mbox, but it's less familiar. The message should arrive in the local mailbox and the remote mailbox, and two bounce messages should appear in the sender's mailbox. User foo controls the address foo as well as all addresses of the form foo-anything . Each address corresponds to a separate file of delivery instructions. If that file does not exist or is 0 bytes long, the systemwide default delivery instructions are used instead.
