Hello WK1966,
Are you using a mail client such as Microsoft Outlook or Outlook Express to download and manage your e-mails?
Essentially, the basics of e-mails is as follows:
When ever anyone sends you an e-mail, for example me, family member or a customer, the e-mail arrives at your mailbox on BT's system, which has been set aside for you. BT retain or hold this e-mail until you open up your program (such as Outlook or Outlook Express), when you do - the program then connects to this mailbox on BT's server and then asks for any new e-mails. If there is BT then send them, through your connection, to your computer.
When you get a message saying that your mailbox is full, it is referring to this mailbox on BT's server and NOT your computer. What you need to do is logon to the BT website at http://myoffice.bt.com , then going to "E-Mail" with the e-mail address and relevant password, once logged in, you may need to click on the purple E-Mail button at the top.
Once logged in, you can then click on your "Inbox" to then delete all the unwanted e-mails in the Inbox folder. It is worth noting that once you have deleted the e-mails to then go to the "Deleted Items" folder and empty that. Once done, that is your mailbox clear.
One thing you might want to do is check to see if "Leave A Copy" is selected on the e-mail program, to do this here are some links below to see, click on the link relevant to you. Mail clients have the option to leave e-mails on the server, or delete them from the server, depending on how it is done. It could be that you have setup to always leave a copy, hence it being full.
Leave A Copy - Outlook 2007
Leave A Copy - Outlook 2003
Leave A Copy - Outlook Express
