struct timeval *timeout,
Perform an Authorized Third Party Signer query regarding a signature.
||dkim_atps_check() is called after
dkim_eom() to check for
Authorized Third Party Signer status for the signing domain. This
involves a DNS query to the sender's domain to ask it if the domain
that signed the message is an authorized third-party signer.
||Message-specific handle, returned by
||Signature handle naming the domain that is being tested for
authorized third-party signer status.
||A pointer to a struct timeval that tells this call
how long it should wait for a reply. A value of NULL will use
the default library DNS timeout.
||A pointer to a dkim_atps_t that will receive the result
of this query.
||The query could not be initiated or completed.
||More than one reply was returned.
