Findings
-
!External report receiver not authorised
The authorisation record for an external rua domain is missing (RFC 7489 §7.1); many receivers then send no reports.
-
!DKIM key below 2048 bits
RSA-1024 is considered too weak (RFC 8301, M3AAWG). Rotate to 2048-bit keys.
-
iDANE active (TLSA with DNSSEC)
All MX hosts publish TLSA records secured by DNSSEC.
-
iBIMI with mark certificate (VMC/CMC)
Logo with a verified mark certificate, shown by Gmail and Apple Mail among others. Requires DMARC enforcement.
