Problem with the old subscription email

Good morning,

some time ago I changed the registration email and therefore access to the account I am using, but emails keep getting to the old email and not the new one.
Can this problem be solved? If so, how?

Please let me know as soon as possible, thank you very much
Greetings!

This sounds familiar. I may have had the same thing happen when I changed my login email.

Which messages are going to the old address? Are any messages going to the new address?
