meillo@118 33 This function is currently (0.2.24) only used for client side SMTP
meillo@118 34 SIZE support (RFC 1870). The flag is_smtp is always true therefore.
meillo@118 35
meillo@118 36 Their definition of the message size in RFC 1870 is:
meillo@118 37
meillo@118 38 The message size is defined as the number of octets, including
meillo@118 39 CR-LF pairs, but not the SMTP DATA command's terminating dot
meillo@118 40 or doubled quoting dots, to be transmitted by the SMTP client
meillo@118 41 after receiving reply code 354 to the DATA command.
meillo@118 42
meillo@118 43 l_cnt (line count) covers '\r' characters which are not present in
meillo@118 44 masqmail's internal format. Dots are also not stuffed in the
meillo@118 45 internal format. Dot-stuffing is ignored in the size.
