Findings
-
!DKIM key below 2048 bits
RSA-1024 is considered too weak (RFC 8301, M3AAWG). Rotate to 2048-bit keys.
-
!DNSSEC not enabled
Without DNSSEC, DNS answers can be forged in transit. DANE requires DNSSEC.
-
iBIMI with mark certificate (VMC/CMC)
Logo with a verified mark certificate, shown by Gmail and Apple Mail among others. Requires DMARC enforcement.
