Hotmail issue

avbos@hotmail.com asked 2 months ago

Hey Hassan,
I followed all steps on your Udemy course and I get 10/10 for email test.
I’ve tried to send some test email from my Roundcube to gmail, Yahoo and hotmail.
The emails went through and delivered to gmail and yahoo but hotmail reject my test emails and said:

Undelivered Mail Returned to Sender

Why and how we can fix it?
 
Here is the text inside those rejected email from hotmail. Also, I’ve tried a couple of times with different hotmail emails but no luck!
 

This is the mail system at host mail.mydomain.com.

I’m sorry to have to inform you that your message could not
be delivered to one or more recipients. It’s attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.
