I'm using Postfix and postfix-policyd-spf-perl (2.005) and this last
couple of weeks I've been experiencing messages from @tiscali.co.uk
being bounced for failing SPF policy.
Problem is whenever I use any online tester and enter the MTA and IP's
etc. they say it passes the policy, so now I'm a little unclear if it
could be something at my end, or a transient error with Tiscali's DNS or
MTAs (and I suspect trying to speak to anyone at Tiscali would take so
long it's simpler to just white list them).
This is an example of the rejection:
http://www.openspf.org/Why?s=helo&id=mk-filter-2-a-4.mail.uk.tiscali.com
&ip=212.74.100.53&r=relay.mira.co.uk
It only seems to happen with Tiscali.
As an example /var/log/maillog shows:
Jul 17 10:10:40 relay postfix/smtpd[3635]: connect from
mk-filter-3-a-1.mail.uk.tiscali.com[212.74.100.54]
Jul 17 10:10:41 relay postfix/policy-spf[3636]: handler
sender_policy_framework: is decisive.
Jul 17 10:10:41 relay postfix/policy-spf[3636]: : Policy action=550
