    1.11 +   Their definition of the message size in RFC 1870 is:
    1.12 +
    1.13 +       The message size is defined as the number of octets, including
    1.14 +       CR-LF pairs, but not the SMTP DATA command's terminating dot
    1.15 +       or doubled quoting dots, to be transmitted by the SMTP client
    1.16 +       after receiving reply code 354 to the DATA command.
    1.17 +
    1.18 +   l_cnt (line count) covers '\r' characters which are not present in
    1.19 +   masqmail's internal format. Dots are also not stuffed in the
    1.20 +   internal format. Dot-stuffing is ignored in the size.
