Default Email Help

On my 8900 I have several email accounts. Everywhere I read I find that the email is suppose to be sent from whatever account you receive it to.
On my 8900 when I hit reply it uses my default for all of my accounts. I want it to automatically reply from the account on which it was received. For example, I have my work account set up on my bb, when I open a message and hit reply, it replies from one of my personal accounts (the default account). I would like to set it to reply from whatever account it is sending from. I have a few businesses that I operate all with different emails, and I want to be able to communicate to my customers from the respective email address, not my default verizon address. Can anyone tell me how to fix this? Everywhere I read, I see my 8900 should already do this, but it doesn't !

You can if you separate your emails. Otherwise just use the dropdown box and change it.
