If alphazulu.com is sending email as foxtrot.com it would be best to
sign the message as foxtrot.com as well so that the signature is
"aligned" from a DMARC standpoint (matches the From domain).
The keys are always in the domain specified by the d= value in the
signature. The best approach is for
Yes of course as that would be the original sender of the email and their
information would also be in your SPF policy. You can change the Sender and
Reply-to headers to be from your domain and mask it a bit better but the
received by headers would show the alphazulu.com mail server.

Glad to help! If you need a low cost DMARC reporting service, I would
recommend www.dmarcian.com

Awesome, Actually one more question. If we allow folks from another domain
to send as us is there a chance anywhere in any of the email "from" headers
it would reveal the "true" domian?
eg..
folks at alphazulu send as @foxtrot.com.
Would @alphazulu.com appear anywhere in the headers?
On Mon,
Thanks guys - very helpful information indeed.

Ideally it is best to use both technologies and then put DMARC on top to
ensure reporting and enforcement of the policies. DKIM cryptographically
signs your messages and SPF informs receiving mail servers of who is
allowed to send on your behalf. You should not think of using only one or

detected a missing SPF would it allow mail through if DKIM is present and
The easiest answer is: Whatever you want. Strictly speaking,
alphazulu.com can send mail on behalf of foxtrot.com using a
alphazulu.com DKIM selector, and that's perfectly valid under DKIM.
However, it won't have DMARC alignment, which is becoming more and more
important, so if alignment is
Lets say my domain is foxtrot.com and we have SPF records for the SMTP
servers on foxtrot.com. Now lets say I have decided I want to allow
alphazulu.com to send mail as foxtrot.I know how to add alphazulu.com to
the SPF but If I wanted to also use DomainKeys or DKIM to authenticate
alphazulu.com
