More Information About Dkim Signature Alignment

DKIM Alignment hinges the domain in your "FROM" header matching the domain used in the DKIM signature (d=domain.com). This uses a relaxed format by default which means that a sub-domain would align as well. If this value is changed to strict in your DMARC record then the domain must match exactly. 

If there are multiple DKIM signatures, only one of them must align for DKIM alignment to be valid.

MxToolbox Delivery Center

This is one problem. Inbox providers check every layer.

Gmail, Yahoo! and Outlook check your email at several layers before it reaches the inbox. Delivery Center monitors and manages every one of them, so you find and fix problems before they cost you delivery.
