Way to align SPF for Google Apps alias domain

g-suitespf

I use Google Apps for Work. Let's say I have:

primarydomain.com

And another alias domain:

aliasdomain.com

As long as I send emails from primary domain both SPF and DKIM result perfectly aligned.

However, when I send emails from alias domain SPF fails to align for a valid reason that it is actually primarydomain.com that is sending emails.

Is there any way to align SPF for alias domain?

Use the redirect modifier to "replace" the SPF record for the alias domain with that of the primary domain.

Thus, the SPF record for aliasdomain.com ends up looking like this:

v=spf1 redirect=primarydomain.com

Note that no all mechanism is required, the final clause of the primarydomain.com record will apply.
