Cant enable mail hosing for my domain

Cant enable mail hosing for my domain

Hi

I have my own domain khanyiselaprojects.co.za

When I try enable mailhosting I get an error "This domain is already associated with this account "k*****s@w*****"."

I think that I tried once before to enable mailhosting and used the wrong email address. How can I register my domain when I made a mistake in typing in the email address and now I need to use the correct email address to enable mail hosting and finish setup of the mail hosting.

Please advise.

Kind regards,

Murray
