PASS SPF record You have an SPF record. This is very good, as
it will help prevent spammers from abusing your domain. Your SPF
record is:
"v=spf1 a mx a:mail.thedacus.net mx:mail.thedacus.net
include:rr.com ~all" [TTL=43200]
I must not have saved it the first time. However still not
working. I checked spfbehavior it is set to 3=* 3: Reject mails
when SPF resolves to /fail (deny)/
Steve thanks so far what is next you think?
ok, good! we're making progress.
from where are you sending your test messages? your error message
leads me to believe that you're sending the message from somewhere
other than mail.thedacus.net or rr.com (and btw, you should be using
"mx:thedacus.net" instead of "mx:mail.thedacus.net", unless you are
publishing MX records for the mail.thedacus.net subdomain (which i
figure you're probably not).
come to think of it, i'd change your SPF record to the following:
v=spf1 mx include:rr.com ~all
as long as your MX record is correct (which it was when i ran a
dnsreport check), i think that'll do it for you and require the least
maintenance over time.
i take it you route outbound mail through rr.com's mail server?
they, incidentally, publish a valid SPF record.
