Ah, although it seems inconsistent at first the rfc5092 does allow a
standard FETCH in this case, my bad, quoting the rfc
The <iuid> refers to an IMAP4 message Unique Identifier (UID), and it
SHOULD be used as the <set> argument to the IMAP4 "UID FETCH"

If i wanted to fix this how would i go about it? I am not yet familiar
enough with the code.

Studying this issue, i also noticed that curl implements the FETCH
FETCH n BODY[...]
while the rfc5092 requires a BODY.PEEK, in detail
The <isection> field is optional. If not present, the URL refers to
the entire Internet message as returned by the IMAP command "UID
FETCH <uid> BODY.PEEK". If present, the URL refers to the object
returned by a "UID FETCH <uid> BODY.PEEK[<section>]" command.
I am more than happy to help.
