451 Message temporarily deferred

I am the administrator of the mail service provider.

I can not deliver mail to aol and yahoo.com from April 24.
Then, I get a message "451 Message temporarily deferred - Abaca "

 

I am in serious trouble.

How can I send mail?

Did you get a resolution for this? My organisation started seeing the same message from the same date.
