monks, i'm having problems using a unix domain socket (i'm trying to connect to spamd using unix domain sockets). when i connect i don't get any errors, then write to the socket and still no errors, but when i shutdown the socket for writng and start reading, mi program just hangs.
i don't really know what am i doing wrong and i really appreciate your help.
the code i'm using is something like this: 
#create the socket
#i'm running spamd like this: 
#spamd -x -ufilter -d --socketpath=/var/spool/filter/spamd.sock

my $DSOCKET = "/var/spool/filter/spamd.sock"
my $socket = IO::Socket::UNIX->new(PeerAddr  => $DSOCKET,
                                Type      => SOCK_DGRAM,
                                Timeout   => 0 )
                || die "No puedo Conectarme a: $DSOCKET:$@\n";

#write to the socket
my $msg = "PROCESS SPAMC/1.2\nContent-length: $ARGV[0]\nUser: filter\n
+\r\n";
print $socket $msg;
my $bytes=0;
#while($line = <STDIN>){
while(<STDIN>){
        $bytes += length($_);
        print "(BYTES=$bytes) ENTRANDO $_";
        print $socket $_;
}

#finish writing:
#i used shutdown i two ways with equal results
#my $val = $socket->shutdown(1);
my $val = shutdown($socket,1);
print "FINISHED($val)\n";

#at this line it hangs.
print "First Line ".<$socket>."\n";
