What does “Not aligned, pass” mean?
"Not aligned, pass" means the SPF/DKIM authentication passed, but the mailfrom/d= domains do not match the “from” domain. In the attached example, although the SPF authentication check passes (i.e the IP address is listed on the mailfrom domain's eu-west-1.amazonses.com SPF record), the mismatch between the mailfrom domain (eu-west-1.amazonses.com) and the "from" domain produces a "Not aligned, pass" result.
