RE: Problem with postfix-policyd-spf-perl

Can I get an explanation in simple terms please?

Obviously we have an SPF record and I know the basic principle i.e. mail
from @mira.co.uk can only originate from relay.mira.co.uk or a couple of
other hosts) in our case as that's how I have our mail flow configured
for all devices.

Where I'm struggling is that in this case the email is coming from an
@tiscali.co.uk address, and the SPF record for tiscali.co.uk seems to
specify a bunch of /24's of which the MTA that caused the problem (one
of several) seems to be in?
