So did I. It failed coming out of the starting gate:

linac% sendmail -bt -Ctest.cf
test.cf: line 692: invalid rewrite line "R*.*!*@*            1.2!3
  lose @-portion"
test.cf: line 693: invalid rewrite line "R*!*.*!*            2.3!4
  strip excess left-hand"
test.cf: line 694: invalid rewrite line "R*.*!*               3@1.2
   invert to @-format"
ADDRESS TEST MODE
Enter <ruleset> <address>
[Note: No initial ruleset 3 call]
> 						/* :-( */

Looking in the log file shows a "NOQUEUE: SYSERR:" associated with
each "invalid rewrite" line.

For reference this is sendmail 5.65a/IDA-1.4.2.
