Subject: [pfx] Re: Getting bounced email that I did not send
DMARC is extra credit; but do configure SPF!
SPF declares who is legitimately allowed to send email purporting to be from
your domain. DMARC gives systems receiving emails which do not conform to the
stated SPF policy instructions on what to do / how to notify you.
You're welcome to look at the SPF published for my domain with "dig m3047.net
TXT" (it's the record that starts with "v=spf1.."). It's simple, it's my two
fixed addresses plus any other MX, if any, configured for the domain. Be sure
to put "-all" at the end.
I took a look at the mx configured for your domain. Making a change to my
v=spf1 txt record, I solved a 2nd problem as well. Now, I can send email
to gmail again.
