Default [Q] Saving sent email (stock app)

Using the stock email app on 4.1.2 (and before I realized there was an option to send a bcc to myself) I sent several emails through Rogers while set up using pop instead of IMAP. So right now I have a number of sent emails that aren't on the server.

I don't want to lose the messages, and while I have figured out that you can open the sent folder, and then individually open and save a copy of each email, I don't want to do that (and it doesn't save the attachments either). I thought maybe I could select them all and forward at once, or save at once, or move them to another folder to sync with the server... but I can't. And I can't come up with a solution.

I thought maybe K-9 would have an option I could use, but I can't figure out how to import the settings from the stock app.

There must be a way to do this besides the one-by-one saving? Thanks for any insight.
