  Log Message:
  -----------
  *-login: Removed enforcing maximum calculated fd limit.

Just use the regular ulimit. Login process has become complicated enough
that counting the exact fd size isn't so easy anymore.

Also apparently this low fd limit is causing errors with new Linux kernels:
pop3-login: Error: fd_send(pop3, 18) failed: Too many references: cannot splice
