meillo@118 38
meillo@118 39 The message size is defined as the number of octets, including
meillo@118 40 CR-LF pairs, but not the SMTP DATA command's terminating dot
meillo@118 41 or doubled quoting dots, to be transmitted by the SMTP client
meillo@118 42 after receiving reply code 354 to the DATA command.
meillo@118 43
meillo@118 44 l_cnt (line count) covers '\r' characters which are not present in
meillo@118 45 masqmail's internal format. Dots are also not stuffed in the
meillo@118 46 internal format. Dot-stuffing is ignored in the size.
