Hello,


The error message you're receiving is a result of the provider being on outlooks blocklist. This is something they're going to need to resolve. As far as emails being received to the old provider, the only way this would happen is if you'd not changed your mx record

First address the problem of who/what is sending the spam. The issue can then hopefully be resolved by asking for the IP(s) sending the email to be removed from Microsoft's outlook/hotmail blacklist. You, or whoever is the admin for the mail server can do this by filling out the form located here: New Support Request
Do not fill out the form until the spam problem is resolved!!
