Outlook & Hotmail Error Hard Fail During Warmup

Hi Hasan, I am using Postal SMTP for sending mails. My mail-tester.com score is 10/10.

My E-mail content doesn't have any spammy words. My subject line has a score of 100 A+. I am fully Authentic with SPF, DKIM, MX, rDNS(PTR), Return Path, etc. Even my spam score is Excellent

But still Hard Fail while sending to outlook or Hotmail. Don't know why? On the other hand, Yahoo and Outlook are receiving my emails in their Inbox. Gmail is also receiving mails but in spam. I know I'll manage it. Outlook accepted mails from my server on the first 2 days but on the 3rd day, there was a Hard Fail from Microsoft's Mail Server(Outlook & Hotmail).

Hi friend, I think this is related to your IP reputation.

or your IP is blocked by ISPs.

connect your server IP and Domain with gmail postmaster tools and check your reputation.

Yes, added on postmaster. I don't know How to configure this. Having issue only with Microsoft Email Services (Outlook, live, msn, Hotmail).

 

Any type of help will be appreciated. I can troubleshot by my own just need some guidelines from you

for Microsoft accounts, sometimes you need to add your SMTP to their list to remove you from the blacklist.
