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?
Go to Solution.
You'll want to reach out to our Postmaster team to get this looked at.
Did you get a resolution for this? My organisation started seeing the same message from the same date.
