You can use your BTMail account to access your other email account.
Log onto BTMail and then go to the settings found by clicking on your username on the right hand side.
Once in the settings click on "Mail" then "Accounts". Click "Add" and enter the relevant details of your non BT email account and follow the prompts. In the protocol section you would be best to select IMAP.
If it does not set up automatically you will need enter some details for your non BT account such as the server settings. These details should be supplied by the non BT email account provider and will no doubt be able to be found with an Internet search.
Once you have the non BT email account set up you will find it showing on the left hand side below your BT email account folders. You can then use it in the same manner as you would if you logged onto it separately. You can check the Inbox etc and send from there.
Once you see it is working OK you can then go into the BTMail settings and cancel the forwarding setting if you wish or leave the forwarding set up as an indicator in your BTMail account that you have received email in the non BT account however you will need to access the non BT account to send your "reply to".
