Recommendations

DKIM alignment (adkim) is unset, so it defaults to r (relaxed). That is fine for most deployments. Set adkim=s explicitly only if your DKIM d= header matches the From: domain exactly.
SPF alignment (aspf) is unset, so it defaults to r (relaxed). That is fine for most deployments. Set aspf=s explicitly only if your Return-Path aligns with the From: domain exactly.
