[MlMt] Downloading utility?

[Dave C]

If MM continues to be “IMAP-only”, I’ve been thinking of  way to 
download my messages from the mail server and store them on my computer 
so as to archive them, if I want to save them all. (After all, the mail 
server has limits to how much storage I’m allowed…)

Anyone else thought about a parallel mail program or downloader utility 
that will download messages after X days after being received?

Thanks,
Dave
