IMAP batch fetch text part of messages

Question

Hey,

I'd like to download the text (that is mime type text/plain, text/html text/richtext) from UID x to UID y.

I have the UID's (and not mailbox IDs).

How can I do something like

FETCH 412444:412500 (BODY.PEEK[TEXT/PLAIN OR TEXT/HTML OR TEXT/RICHTEXT])

Thanks!
