The following worked:
<code>
import sys
import fileinput
def write( s ): print( s, end = "" )
msg_id = 0
f = open( "nul", "w" )
input = sys.stdin.detach() # binary
while True:
line = input.readline()
if len( line ) == 0:
break
elif line.decode( "ascii", "ignore" ).startswith( "From - " ):
msg_id += 1;
f.close()
print( msg_id )
f = open( "msg_{0:0>6}.txt".format( msg_id ), "wb+" )
else:
f.write( line )
f.close()
</code>
