This thread is a little old, but I noticed a change that could be made with regards to the gmail/yahoo sent emails showing up in the inbox(es).
If you have configured gmail/yahoo in BIS, you'll need to filter out all emails coming from the
![[email address]](?emailimage=d6ad5bca879e8560e9e6d9e55ed1def9)
address only. Add this filter for each email account added to BIS.
If you continue to receive sent emails from the gmail/yahoo accounts, go to gmail/yahoo and turn
off forwarding as BIS is pushing and syncing your emails both ways. I checked this and I know it works. This allows you to send emails to yourself (like for documents you need and don't want to take your laptop on the road for example) on an as needed basis.
If you have any questions, post here. I'll try to explain further if you don't get it.
