    Thanks for the link!

    I checked it and findings were following:

    SPF Record Check - no issues reported
    DKIM - that i could only check for gmail and not outlook, according to that link...
    DMARC
    Only 1 founding: Policy Not Enabled DMARC Quarantine/Reject policy not enabled (mxtoolbox)
    but this seems to be okay, as it just shows that there is not additional protections set up..?!

    Thanks

      Hi,

      an update reg. the issue.

      I now tried to send email to myself (to my gmail account) , just a test email and I can`t even do that. Same error message popping up once again.

      What on earth is going on? Anybody??

      Thanks!
