A little more information:

This bug results in Mozilla and pine never rendering the message, since dovecot lies about how much data was really sent, as seen in the following log in which only 394 bytes (rather than the 10240 dovecot is claiming to send) are returned:

8 UID fetch 94 (UID RFC822.SIZE BODY[]<10240.10240>)

• 24 FETCH (UID 94 RFC822.SIZE 20873 BODY[]<10240> {10240}
