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

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