FETCH RFC822 response lacks RFC822 information in icloud IMAP server

[epilys]

Server replies successfully, but the untagged FETCH line lacks RFC822 part. A workaround is to fetch BODY[] instead.

I tried to find something quotable but gave up. NO - fetch error: can't fetch that data indicates it's an error. But I feel we could miss something... Best bet is that it's an error, though.

What do you mean by "something quotable"?

I'm scared by IMAP and not sure if responding with less data items than requested could still be valid.

Maybe the "NO" response is reserved for the case when no data items at all could be constructed but the server knows they exist.

I hoped to find a sentence in the RFC like "a server MUST respond with all data items that were requested" but there is no clear answer so far.

I know this is a stretch but I don't trust IMAP :P

There was no "NO" response actually according the user, but a successful one. It must be a bug
