I cannot seem to get a SPF record working for a client of ours, Google mail keeps failing on the lookup.
My SPF record is
v=spf1 a ip4:188.8.131.52 include:mx1.helloevery1.co.uk include:_spf.google.com include:smtproutes.com include:smtpout.com
The clients main mail server are
smtproutes.com and smtpout.com
These are working fine, SPF passes as expected.
mx1.helloevery1.co.uk is our mail server. It is a simple ISPConfig Postfix setup. We send all mail through 1 account, let's say that is "email@example.com".
There is a username and password set up to send through but we change the "from" address in our application. The from address is "firstname.lastname@example.org".
"email@example.com" is not set up on mx1.helloevery1.co.uk. It is only on the client servers.
When I send through my SMTP server from the site, I am receiving the following error when I send to my email account.
Received-SPF: permerror (google.com: permanent error in processing during lookup of firstname.lastname@example.org) client-ip=184.108.40.206;
Authentication-Results: mx.google.com; spf=permerror (google.com: permanent error in processing during lookup of email@example.com) firstname.lastname@example.org
This looks like it is trying to lookup the domain on my SMTP server (where is not is configured). If I were to set up the domain on my SMTP server and create an account then when I send through my SMTP server then it will try to deliver it locally.
I've always assumed that SPF was just a verification tool to say which server is allowed to send but never really took into account the email it is coming from.
I'm stuck as I can't find a resource on SPF record creation that I can relate to
