Hello All,
I have been doing a lot of reading around SPF, DKIM and DMARC and i think i have digested most of the information and how all three work in the email world. However one question i couldn't find is, What will happen to an email if SPF failed and DKIM passed and vice versa? Will that email be delivered normally?
I have setup DMARC for our domain and within the reports i'm seeing some emails from google/yahoo etc passing SPF and failing DKIM and vice versa, does this mean the emails are getting delivered?
Thanks
SPF and DKIM question!!
Re: SPF and DKIM question!!
Here is what I call the DMARC formular:
DMARC pass = (SPF pass AND identifier alignment) OR (DKIM pass AND identifier alignment)
That is to say, you only need either SPF or DKIM to pass and have identifier alignment.
However, passing email authentication checks doesn't necessarily mean your emails are delivered since email deliverability also depends on other factors such as sender reputation, content spamminess, etc.
