You can forward an email account of a domain you have with Fullhost using the fullhost Email Forwarding tool
(This tool should only be used to forward emails, if the emails themselves are not hosted with Fullhost. If the emails are hosted in a Fullhost shared/managed server, you can forward it through cPanel as described here: https://manage.fullhost.com/knowledgebase/368/How-to-forward-an-email-to-Gmail-Yahoo-or-other-email-service-providers-.html)
Fullhost client area > Domains > select your domain
If you haven’t already ordered this addon, you will have to order the addon first.
On the left-hand side menu, you can see the option “Addons”.

Here you can see available addons. To redirect a domain to another domain, you need to order the addon ”Email Forwarding". No need to worry, this tool won’t cost you any money, it will just invoice you $0.00CAD. Click “Order” and then “Buy Now for $0.00CAD/Year”


Now go back to the previous page and you will see a new tool called “Email Forwarding”.

Here you can forward individual email accounts to a different email account.

Finally, change the Nameservers of the domain to the following.
ns10.fullhost.net
ns11.fullhost.net
ns12.fullhost.net
Wait for some time for the DNS to complete propagation and the emails will start getting forwarded to the destination address.
