Opening a message must be quick.
The /body (and HTML body) response must not be blocked by checks that can run afterwards.
Describe the solution you'd like
Defer the phishing check off the /body path, the same way DKIM and itineraries are deferred, so it no longer delays body delivery. The deferred check must reuse the already-fetched/cached message rather than trigger an extra IMAP fetch.
