qconfirm is an implementation of a delivery confirmation process for a mailing list or mail address. It is invoked by qmail-local through a dot-qmail file, and can reduce the amount of junk mail hitting a mailbox or the mailboxes of mailing list subscribers. qconfirm performs this delivery confirmation process either sender based or message based. When used for a public mail address, not a mailing list, qconfirm is capable of detecting follow-ups on mail messages originated from this mail address, and doesn't request delivery confirmation is this case. qconfirm also is able to identify delivery confirmation requests from recipients of mail messages, and automatically confirms the delivery if desired.
