Copy of Sent Emails Not on Server

view story

http://forums.androidcentral.com – I recently switched from BB to S-s3 Android Verizon. My yahoo email account and work account run thru the native email account that came with phone. However there are no copies of sent emails on either my yahoo email account or work email account. This was I accustomed to from my BB. This is critically important since I am on mobile all day and need sent items to accessed thru my PC when I get home. Is there a fix for this ? Seems you cannot change this on the email setting like you could BB. Can any one help here? Thanks in advance (HowTos)
