    Hi,
    I need your help
    I have configured a new server with ispconfig 3.0p1
    I can't send email to outlook/hotmail, i have this message
    I verified DKIM, SPF, DMARC and i have configured my ip to the microsft SNDS

    Are you an idea ?

    Thanks
    Best regards

    The message tells you what to do:

    If your IP is on the MS Blocklist, then this can't help.

    Are you on OVH? I had this problem recently. As till told you, there is nothing you can do but Talk to your provider

    Yes i'm in OVH. OVH said to contact Microsoft. I open a ticket to microsoft and i received a request for document for him.

    But i found an issue to the dmarc report from Microsft
    In the email was reject, i have the DKIM in the header.
    It's possible it's an issue with DKIM and PHPmailer ?

    Best regards

    Don't waste your time. The message is clear: your IP is blocked by Microsoft. There is nothing you can do but send from another IP outside of that blocked network
