Respond to delivery notice requests
in .qmail: |qreceipt youraddress
When a mail message arrives with youraddress listed in a Notice-Requested-Upon-Delivery-To header field, qreceipt sends a success notice back to the envelope sender.
WARNING: If you create a .qmail file to enable qreceipt, make sure to also add a line specifying delivery to your normal mailbox. For example:
/home/joe/Mailbox
|qreceipt [email protected]
