Gracias (that's pretty much the only spanish I know)
Are you sure my prognosis is similar to what's talked about in these two threads? My problem isn't that I'm getting duplicates. If I don't reply or forward an email from my computer, the original doesn't get resent to me (the duplicate is not of the sent item, but rather of the original email, no matter how long ago the original copy was received). Also, if I reply to or forward it from my blackberry, it doesn't happen. Only when I reply to or forward something from my computer does that something get resent to me on my blackberry.
By the way, it's neither a yahoo nor a Gmail account. Thoughts?
