SendGrid can not send emails from @yahoo.com

I use the SendGrid as 3rd party email delivery service. I find that Emails can not send from yahoo. For example, sending emails from @gmail.com to @yahoo.com and from @outlook.com to @yahoo.com are worked, but sending emails from @yahoo.com to @gmail.com or to @outlook.com are not worked. How to fix this problem?
THANK YOU !
