To process the mail, in the mail-filter.php of the whups package, in a
memory-frieldly way, its necessary to read the input in blocks, write them
to a file, read the next part etc. instead of reading the whole message into
 a variable at once. As now happens:

$text = $cli->readStdin();

So I suppose an extension of the CLI in the framework, an extra function:

$cli->readStdinByteRange (&$output, &$read, $bytes)

It returns true if there is more data, and false if the feof is reached. 
In this way it can be used in a loop liike this one:

while ($cli->readStdinByteRange (&$output, &$read, $bytes)) {
   fwrite($handle, $output);
}

An patch containing an little enchangement voor the CLI packages is
included.
