When fetching, messages are sent to plumber as soon as the ENVELOPE part is read. The date field of the message is sent when the INTERNALDATE part is read and there is no guarantee that this will be read before the ENVELOPE. This bug can be observed when using faces(1) which will retrieve messages with a null date and then always display a 'Jan 1' date instead of the correct one. The fix is to simply send the message to plumber after having read all parts, thus ensuring the message is complete.

According to RFC 3501 the arguments to the LOGIN command should be quoted strings (or length prefixed string literals). Without quoting, authentication to some IMAP servers (e.g. Dovecot) will fail.

UTF-8 searches with the SEARCH command must be conducted in two steps: the first sends the SEARCH command with the length of the UTF-8 encoded string and the second sends the literal search term. The searches need to not be quoted. R=rsc, david.ducolombier, rsc, 0intro CC=plan9port.codebot https://codereview.appspot.com/13244043
