-nonotify allows to disable notifications for mailboxes.

-notify can be used to re-enable notifications for a previously disabled
mailbox.

get notified about new mail in their work mailbox, but not get disrupted
by new mail received from the mailing list.

This patch allows individual configuration for all mailboxes.
