qconfirm-return - handles bounces from qconfirm-check(1)
qconfirm-return expects QSBMF
(qmail-send bounce message format) bounce messages and processes them. It
tries to extract the recipient address that caused the bounce from the
failure paragraph and the unique key that qconfirm-check(8) has created
for delivery confirmation for messages from this address from the original
message (the included qconfirm-check(8)’s confirmation request message).
- in .qmail:
- |qconfirm-return [-n limit] [dir]
qconfirm-return fails to do so, or the key in the original message does
not match the key qconfirm-check(8) has created for this address, or the
envelope sender is not empty, it prints a warning and exits 0.
qconfirm-return notices that this address bounces. If qconfirm-return sees
that this address already has bounced before, it tells qconfirm-check(8)
to silently drop the message from this sender address the next time qmail
tries to deliver it (exception: see the -n option).
If qconfirm-return was
able to successfully parse and notice the bounce message, it exits 99,
and so tells qmail-local(8) to ignore all further delivery instructions.
qconfirm-return exits 111 on error.
- -n limit
- Limit. limit must be an
integer; if this option is given, qconfirm-return notices addresses that
bounce limit more times before telling qconfirm-check(8) to silently drop
the message from the sender address. Default is 0.
- qconfirm directory.
qconfirm-return uses the qconfirm directory dir for checking pending addresses
and noticing bouncing addresses. Default is .qconfirm.
