Ok, with /bin/tcsh as the login shell the results are the same. Also tried
csh and sh just to make sure.

# su mailman
%limits
Resource limits (current):
  cputime          infinity secs
  filesize         infinity kB
  datasize           524288 kB
  stacksize           65536 kB
  coredumpsize     infinity kB
  memoryuse        infinity kB
  memorylocked     infinity kB
  maxprocesses         5547
  openfiles           11095
  sbsize           infinity bytes
  vmemoryuse       infinity kB
%

These limits are pretty standard, right?
