You can have with gmail where all the emails directly fwd to you, and delete from inbox.
Oh whoops wont work, never mind
You can forward and also keep in original email address.
The main features I am looking for are:1. The ability for parent to remotely approve or deny any email sent to children, before it gets to their inbox.
Depending on whether you want them to know, you can do that and then email it back if it's approved...?
OT, is it possible to forward emails from a specific sender and not all other emails? (With gmail or yahoo.)E.g. I'd like only the emails I get from groupon to be forwarded to another address. ..
You should e able to do that with a filter no?
+1 - very simple to do in gmail with a filter
Go to Settings, then to Filters, type in the email address you want, and set it to be forwarded.
