Email support help needed!

[jim berry]

Some time ago exploring ubuntu documentation I subscribed to receive 
posts and replies on ubuntu questions. Very helpful at times, when I'm 
not using my computer regularly I'm overrun with hundreds of emails of 
information.
Not remembering where I turned this on, I'm at a loss to turn it off 
when not desired.
I'm using hotmail if that matters and any assistance would be greatly 
appreciated.
