Hello
I have an SPF record created in DNS for my domain. In my main.cf config file
for Postfix I have the following SPF settings:
spf_received_header = yes
spf_mark_only = no
smtpd_recipient_restrictions = peject_spf_invalid_sender,
permit_spf_valid_sender,
smtpd_sender_restrictions = reject_spf_invalid_sender,
permit_spf_valid_sender
Is the above config correct to reject received emails that is NOT being
delivered from the specified IP addresses in SPF?
I basically want to reject/fail emails that are not coming from the correct
IP address specified by the domains SPF record.
Also, recently I received one of these:
This is a spf/dkim authentication-failure report for an email message
received from IP 14.16.26.208 on Sun, 11 Jan 2015 00:32:42 +0800.

Does this mean SPF has failed as it said that the delivery results says
delivered? I didn't receive this email so maybe its fake? What is the above
message?
Thank you.
