Hi all, we have changed from cpanel emails hosting to a email hosting service on our website hosting provider .
since we have made those changes the admin notification emails dont come thru. its been working without any issues when we had the simple cpanel email account , but with the upgradet hosting service it is not working.
this is the error message reply from our hosting website:

we have now changed email accounts back to cpanel hosting and its working fine again.
any idea what would cause this?
it is an event notification form to the admin email, which i used the same email address in the from and in the to email section.
thanks in advance
