How do I change my Yahoo email on my Blackberry?

My Yahoo Email is suddenly started being forwarded to a non-Yahoo account. How do I stop it ???

• I had tried in the past to have my Yahoo email forwarded to my blackberry... newer yahoo.ca accounts seemed to work ok but my old yahoo.com account although configured the same did not work... Last night some time after 5:30 PM EST my yahoo.com email started being forwarded to my blackberry... this would be OK but it is deleting it from my yahoo inbox... 1) How do I change the configuration. ie Stop it deleting from my yahoo inbox? 2) Why did this suddenly start working... I have been with yahoo for a long time but it is starting to annoy me when I cannot get any answers and can;t talk to anyone... Can somebody please help...

• Answer:

  So far, this looked like it worked for me. 1.) I logged into my yahoo!mail account; 2.) Clicked "options" on the right side; 3.) Clicked "account information" on the left side; 4.) Clicked "edit" from the MEMBER INFORMATION heading; 5.) Changed the "Alternate Email 1" entry to another address, but did not verify; 6.) Clicked "finished" I sent a test message and checked my inbox. It arrived and wasn't forwarded. My mail began forwarding around the same times as yours. Anyone know why this is happening? Filters in other address started re-forwarding the mail. Could have been very embarrassing.
