Code:
if (MESSAGESIZE < 0)

How will that ever be true ?

You might want to reconsidder this part
Code:
bzero(msg, MESSAGESIZE); 
numbytes = read(sockfd, msg, MESSAGESIZE); 
if (MESSAGESIZE < 0)  
perror("ERROR reading from socket"); 
printf("Recieve from server: %s", msg);

you might want to do a loop, where you read from the socket, then write to your output file, when the numbytes is 0 or less you're done reading and it's time to close the output file..

I'm not sure if this has anything todo with the error, but one failure I see is:
Code:
fwrite(msg, sizeof(msg[MESSAGESIZE]), sizeof(msg)/sizeof(msg[0]), out_file);

considder what the sizeof(msg[MESSAGESIZE]) will be, if the read part dosn't fill in the entire msg arrray.

And the part where you open the output fie for writing isn't correct, you open it, try to write to it, then has an open issue trying if it is capable of beeing opened.

SYNOPSIS

PARAMETERS

       The contains the following parameters:

       rmsocket  A  flag  that	indicates whether the library must try to remove any existing UNIX domain socket before attempting to create a new
		 socket.

DESCRIPTION

       The routine is used to create the socket specified previously by a call to the routine, which is the interface between Mail Transfer Agents
       (MTAs) and the filter.  The routine allows the calling application to ensure that the socket can be created.  If is not called, the routine
       does it implicitly.

       The routine is called only from program mainline before calling the routine.

RETURN VALUE

       Following are the possible reasons when the routine fails and returns

       o  The interface socket is not created.
       o  When rmsocket is true, either the socket is not examined or the socket exists and cannot be removed.
       o  The routine is not called.

AUTHOR

       The routine was developed was the Sendmail Inc.
