Spam is getting pushed to your browser or to your email?
If to your browser, I have no idea what you mean.
To your email, place a spam filter on your email server. That is the best method there is, to kill the spam before it gets to you.
If you are using a
address, don't. They famously attract spam because the spambots out there easily create addresses based on the blackberry.net address.
More detail about how the spam is getting to you and how you are configured would help.
