=head1 NAME
FML::Parse - parse the incoming message
=head1 SYNOPSIS
$msg = new FML::Parse $curproc, \*STDIN;
=head1 DESCRIPTION
FML::Parse parses the incoming message. C<new()> analyses the data
injected from STDIN channel, by default, and split it to a set of mail
header and body. C<new()> returns a C<Mail::Message> object.
=head1 METHODS
=item new( $curproc, [$fd] )
C<$fd> is the file handle.
Normally C<$fd> is the handle for STDIN channel.

# Arguments: OBJ($self) OBJ($curproc) HANDLE($fd)
# Side Effects: none
# Return Value: OBJ
sub new
{
my ($self, $curproc, $fd) = @_;
my $me = {};
bless $me, $self;
return $me->_parse($curproc, $fd);
}
# Descriptions: parse message read from file handle $fd
# Arguments: OBJ($self) OBJ($curproc) HANDLE($fd)

sub _parse
{
my ($self, $curproc, $fd) = @_;
use Mail::Message;
my $msg = Mail::Message->parse( {
fd => $fd,
header_class => 'FML::Header',
});
# log information
my $header_size = $msg->whole_message_header_size();
my $body_size = $msg->whole_message_body_size();
Log("read header=$header_size body=$body_size");
if (defined $msg->envelope_sender()) {
my $pcb = $curproc->{ pcb };
if (defined $pcb) {
$pcb->set('credential', 'unix-from', $msg->envelope_sender());
}
else {
