    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mxa-00a30001.gslb.pphosted.com, mxb-00a30001.gslb.pphosted.com
    #11

    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: selector1 (1024 bits), selector2 (1024 bits). Rotate to a 2048-bit key.

    Policy in testing mode
    TLS · With mode: testing, senders only report TLS problems (via TLS-RPT) and still deliver without TLS. Switch to mode: enforce once reports are clean.
    #33
  • !
    MX hosts missing from policy
    TLS · These MX hosts are not listed in the MTA-STS policy (mx: spamfilter1.west-vlaanderen.be, spamfilter2.west-vlaanderen.be): mxa-00a30001.gslb.pphosted.com, mxb-00a30001.gslb.pphosted.com. This will break delivery once the policy is enforced.

    No certificate (a=)
