    My email is rejected by microsoft


    Dear all,
    emails that are coming out from my server domain is rejected by microsoft:

    This message was created automatically by mail delivery software.

    A message that you sent could not be delivered to one or more of its
    recipients. This is a permanent error. The following address(es) failed:

    myemail@hotmail.com
    host mx3.hotmail.com [65.55.33.119]
    SMTP error from remote mail server after end of data:
    550 5.7.0 (COL004-MC5F17) Unfortunately, messages from (xx.xx.xx.xx) on behalf
    of (mozaik.club) could not be delivered due to domain owner policy restrictions
    However, when I request to remove the ban to hotmail sender support, he cannot help,
    he gives guidelines how to avoid ban (brand the email, formatting best practice, junkmail
    reporting program, etc), which I think I did all that.

    Now I am stumped. What is the starting point to troubleshoot this?

    regards

    That domain name is configured using SPF to only allow emails being sent from one particular mail server, identified by an IP address. You need to amend the record to also allow that xx.xx.xx.xx IP address given in the error message.

    Amend the record? how?

    By the way Im using my virtual private server for my email server, should I use email service instead to avoid this kind of problem?

    An email service would (could) avoid this problem, but you do not have to use one.

    1. Does your VPS have a static IP address?
    2. Do you know how to edit DNS records for your domain?
    3. Did you set up SPF yourself? Who did? Can you and your email server support DKIM validation instead, which can be more flexible than SPF and can more easily support email servers using dynamic IP addresses?
