googling for "tee exit code" i found this that works (source): 
(/bin/foo ; echo $? >RES)| tee -a $LOGFILE
export ERR=$(cat RES)

I also found this posting (see also man bash and search for PIPESTATUS) that says that this will work: 
  $ cat test
  #!/bin/bash
  echo foo
  sleep 2
  echo bar
  false
  
  $ ./test | tee blah
  foo
  [.. seconds later..]
  bar
  
  $ echo ${PIPESTATUS[@]}
  1 0

  # (so ${PIPESTATUS[0]} should give you the return of the first comma
+nd).

But i was unable to get it to work (PIPESTATUS seemed to always have just one element of 0)...
