No, that is incorrect.
With POSTFIX, the -f and -r options do exactly the same thing:
case 'f':
sender = optarg;
break;
...
case 'r': /* obsoleted by -f */
sender = optarg;
break;
If you look in your logging, you may find that you are handing the
mail to something other than POSTFIX.
POSTFIX submissions looks like:
pickup[xx]: yyy: uid=1001 from=<wietse>
cleanup[zz] yyy: message-id=<[email protected]>
Wietse
