Forgotten password on business hosting

Forgotten password on business hosting

Hi, set up a business hosting account for a domain I control recently. Have set up a number of emails and passwords but I've either forgotten or written down the password for the main superuser account.

I can login to all the other email accounts but they don't provide access to the control panel.

I've asked for a password reset but the system can't do that as I can't access the account to process the password reset.

There is an email listed to contact for further information but it's getting bounced back - support@zohoaccount.com

Any idea how I can gain access to the hosted email accounts?

I do control the domain as it's registered to me and did verify by the uploaded script process.

Any assistance gratefully received!

Thanks

Chris
