#
|
|
# Parameters understood:
|
|
#
|
|
# config (required)
|
|
# autoconf (optional)
|
|
#
|
|
# Gives the result of the verification. The following values are possible:
|
|
#
|
|
# pass
|
|
# Returned if a valid DKIM-Signature header was found, and the signature contains a correct value for the message.
|
|
#
|
|
# fail
|
|
# Returned if a valid DKIM-Signature header was found, but the signature does not contain a correct value for the message.
|
|
#
|
|
# invalid
|
|
# Returned if no valid DKIM-Signature headers were found, but there is at least one invalid DKIM-Signature header. For a reason why a DKIM-Signature header found in the message was invalid, see $dkim->{signature_reject_reason}.
|
|
#
|
|
# none
|
|
# Returned if no DKIM-Signature headers (valid or invalid) were found.
|
|
#
|
|
# In case of multiple signatures, the "best" result will be returned. Best is defined as "pass", followed by "fail", "invalid", and "none".
