We're having some email deliverability problems and I've tracked it down to a couple of issues:
- SPF/DKIM records are mismatched
- Our app is sending mail from one domain on behalf of another without permission
Our app is set up to send mail through a mail server at companymailserver.com, but we're changing the FROM address to come from support@companyname.com.
I can't quite figure out what needs to be done to authorize companymailserver.com to send mail on behalf of support@companyname.com
I know I need to handle this with Domain Delegation, but I'm at a loss on how to actually set that up.
If someone can point me in the right direction I'd be very grateful!
