As a side note, it’s also from your carrier’s BIS site that you can also edit the “Sent from my BlackBerry smartphone” type message that appears at the end of all of your outgoing messages as well.
Setting up filters on your BlackBerry is a smart decision for anyone who receives large amounts of mail that does not have to be read or responded to right away. Don’t let your messages overwhelm you, just take a few minutes to establish filters and you once again can feel in control of your BlackBerry.
