RE: Problem with postfix-policyd-spf-perl

Thanks that makes sense - what confused me though is that I thought SPF
only worked at a domain level i.e. why is it looking up an SPF (TXT)
record for an individual host?

	What John pointed out is that the sending mail server is
apparently telling the world that it's name is
"mk-filter-3-a-4.mail.uk.tiscali.com."  The SPF record for
"mk-filter-3-a-4.mail.uk.tiscali.com" is telling the world that it's IP
is 212.74.100.42, but the message is coming from a different IP,
212.74.100.54.  It is the SPF record for
mk-filter-3-a-4.mail.uk.tiscali.com that is causing the failure, not the
record for tiscali.co.uk.  Therefore the fail result is correct.

the SPF record for mk-filter-3-a-4.mail.uk.tiscali.com is "v=spf1 a
-all"
the A record for mk-filter-3-a-4.mail.uk.tiscali.com is 212.74.100.42
You are receiving mail from 212.74.100.54
SPF seems to working correctly!
