SPF Handling for subdomains

Post by dbacher » Wed Oct 21, 2020 1:27 pm

Intuit specifies this SPF for intuit.com:
v=spf1 include:servers.mcsv.net include:_spf.salesforce.com include:_spf1.intuit.com include:_spf.centercode.com ip4: ip4: ip4: ip4: ip4: ip4: -all

I received these headers in a Phishing email:

Code: Select all

Received-SPF: none (battlebazaar.net: o3.e.notification.intuit.com does not designate permitted sender hosts)
Received: from 93-56-16-241.ip287.fastwebnet.it ([]) by battlebazaar.net with

So it looks to me like this should have found the SPF record and rejected the message, unless I'm missing something. I'm on 10.30, will install 10.31 - but won't know if it impacts unless the phisher sends another one.
