   5 # This router handles aliasing using a traditional /etc/aliases file.
   6 #
   7 ##### NB  You must ensure that /etc/aliases exists. It used to be the case
   8 ##### NB  that every Unix had that file, because it was the Sendmail default.
   9 ##### NB  These days, there are systems that don't have it. Your aliases
  10 ##### NB  file should at least contain an alias for "postmaster".
  11 #
  12 # This router handles the local part in a case-insensitive way which
  13 # satisfies the RFCs requirement that postmaster be reachable regardless
  14 # of case. If you decide to handle /etc/aliases in a caseful way, you
  15 # need to make arrangements for a caseless postmaster.
  16 #
  17 # Delivery to arbitrary directories, files, and piping to programs in
  18 # /etc/aliases is disabled per default.
  19 # If that is a problem for you, see
  20 #   /usr/share/doc/exim4-base/README.Debian.gz
  21 # for explanation and some workarounds.

  23 # hcoop-change: Look up the local_part and domain, not just the
  24 # local_part.
