I do this a different way, by having a router which un-munges the
address (we outsourced our student email to Google recently so this is
very valid for forwarded mail):

staff_and_student_system_aliases_google_forwarder:
  driver = redirect
  domains = OURDOMAINS
  data = ${lookup mysql{\
                        select target from map where lhs =\
                       '${quote_mysql:${sg\
                                          {$local_part}\
                                          {\N\+caf_=.+\N}\
                                          {}\
                                       }\
                         }'\
                       }\
           {$value}fail}
  file_transport = address_file
  pipe_transport = address_pipe
  allow_defer

The regex replace in the middle there strips the "+caf..." part from the
address, and the OURDOMAINS macro limits this to, well, our domains.

No rewriting necessary.
