Done :)

For some reason neither 
```sh
mflag -d -S "$draft" | mrefile - "$outbox"
``` 
nor 
```sh
mrefile -v "$draft" "$outbox" | mflag -d -S -
```
 worked for me. Both of these made a copy of the draft file in the destination directory without flags and changed the flag from 'D' to 'S' of the original file.
