35 ** This function is currently (0.2.24) only used for client side SMTP

37 **
38 ** Their definition of the message size in RFC 1870 is:
39 **
40 ** The message size is defined as the number of octets, including
41 ** CR-LF pairs, but not the SMTP DATA command's terminating dot
42 ** or doubled quoting dots, to be transmitted by the SMTP client
43 ** after receiving reply code 354 to the DATA command.
44 **
45 ** l_cnt (line count) covers '\r' characters which are not present in
46 ** masqmail's internal format. Dots are also not stuffed in the
47 ** internal format. Dot-stuffing is ignored in the size.
