Ok, but mailman is a nologin user. Should I change this temporarily to check?

# su mailman
This account is currently not available.

I'm not sure about the syntax but limits -U mailman doesn't seem to make
the user mailman, but just use the class default.

# limits -U mailman
Resource limits for class default:
  cputime          infinity secs
  filesize         infinity kB
  datasize         infinity kB
  stacksize        infinity kB
  coredumpsize     infinity kB
  memoryuse        infinity kB
  memorylocked     infinity kB
  maxprocesses     infinity
  openfiles        infinity
  sbsize           infinity bytes
  vmemoryuse       infinity kB
