at.sovrn.mail.email

One message in a mirrored mail folder, after the JMAP Email (RFC 8621 §4), with the raw RFC 5322 message as a blob. Content is immutable. Header fields longer or more numerous than the limits here are shortened; raw always has the whole message. The record key is the base32 (lowercase, unpadded) of the first 20 bytes of the raw message's SHA-256, so it is the same in every folder and can be recomputed from an export. The folder is the space, so there is no mailboxIds; keywords are not mirrored.
