here's how i've setup my main account that i'm getting double mail on:
my main email with my own subdomain is pushed/forwarded to my gmail account. then the blackberry BIS checks the gmail and pushs it to me. I don't have gmail confiugred to forward any mail to my .cingular.blackberry.net address.
i do have a filter on my gmail
i also have the "from" filter setup on the gmail address in my BIS account to get rid of any sent dupes.
any thoughts? thanks for all the help...this is a pain.
