relay not detected

[Pedro David Marco]

Hi,
i have spam emails with a Received line like this:
Received: by 9-30-239-23.uocdn.net (Postfix) with ESMTPSA id 693A0C56B with 
(unknown [158.69.130.12]) ; Sun, 20 Nov 2016 21:06:55 -0300
there is no parsing perl code for lines like this in Received.pm module so the 
relay 158.69.130.12 is never checked
is this normal?

Pedro.
