Can I add a filter to BIS from the device?
 

Am tired of getting spam from the same old "software distributors" who use 400 different variations of the same address, and every time I have to add a new filter via my computer BIS console. I don't think it exists, but might there be a simple way to add a filter to an email that arrives in your device inbox, without using a computer?

are you using the standard (or whatever the variation is for your carrier) address?
It is advised you dont do this for reasons as you have found out, it has no spam filtering at all.

I know you can on the Bold (on AT&T at least) with the recent change to the Personal Email Setup interface (more like an on-device app vs. logging in through WAP). Not sure about the 8900 on T-Mobile. If clicking the Email Setup icon takes you directly to a screen asking for BIS login credentials without using the WAP browser to load the page first, you should be good to go.

If it does: Log in, scroll to the email address you want to add filters to, and either hit the menu key or click the trackball. Filters should be one of the options. It should be self explanatory from there.

If not: You're probably stuck with the on-PC method for now. (n)

AFAIK, the filter option on the device's menu is only for BES filters.

I set up a filter on one of my accounts through BIS on the device and it's working fine. I just set up another one to be sure, and that one is working too. I'm not sure if they just added that functionality with the BIS 2.7 upgrade that occurred over the weekend though. Never tried setting up a filter on the device until today.

Have you thought of filtering your mail to a GMAIL account?
They have some of the best spam filters, and its push mail to the Blackberry
