It should probably talk a bit what it means that a message is "seen by
the recipient". For example:

1. IMAP client is IDLEing and downloads the message headers immediately.
Can it be recalled? (yes?)

2. IMAP client downloads one (or more) MIME parts of the message and
sets \Seen flag. Can it be recalled? (no?)

3. IMAP client downloads one (or more) MIME part of the message but
doesn't change flags. Can it be recalled? (no?)

4. IMAP client downloads message headers and sets \Seen flag. Can it be
recalled? (yes?)

5. POP3 client downloads the message but doesn't delete it. Can it be
recalled? (no?)

Also there's a security/privacy issue that's not mentioned: I don't want
anyone to know when I've read an email they sent. This could be used by
whatever spies to find out when exactly I'm reading my email by looping:
send message, recall message, send the message again, recall again, etc.

Should be ok.
