  15 # Change locally-generated Message-Id: and Resent-Message-Id:
  16 # headers to world-unique values.
  17
  18 # Notes:
  19 # Change every occurence of "home.dom" to your home domain.
  20 # Change every occurence of "uniqie.remote.dom" to some unique value.
  21
  22 # Unique values, as Vadik explained in his message to exim-users,
  23 # can be chosen in different ways:
  24
  25 ### The ideal way is to choose "hostnames" in existing domains whose
  26 ### admins you know, and you will be sure that no hostname ending
  27 ### with ".nonexistant.friendly.dom" will ever appear on this planet,
  28 ### not even on someone else's message IDs.
  29
  30 ### Another ideas include putting after your hostname things like:
  31 ### .972.2.6412694.phone
  32 ### .29.32.columbia.street.jerusalem.96583.israel.addr
  33 ### .1122.3576.3847.1446.visa.01.2002.expiration.date.vadim.vygonets.name.credit.card

  35 # This snippet provides to schemes to do such rewriting.  The
  36 # first scheme is to have mapping from local hostnames to unique
  37 # "Message-Id domains".  The second scheme is to use one unique
  38 # "Message-Id domain", inserting the original "domain" into the
  39 # "local-part" of the new Message-Id header.
  40
  41 # Precaution
  42 headers remove "X-Vygo-Net-Temporary-Message-Id"
  43
  44 # Change Message-Id:
  45 if "${if def:h_Message-Id: {yes}}" is yes and
  46     ${lc:${domain:$h_Message-Id:}} is    "home.dom" or
  47     ${lc:${domain:$h_Message-Id:}} ends ".home.dom" then
  48 # This is if you want to have a file mapping each hostname to a unique
  49 # Message-Id domain part, or, if it fails, preserves the original domain part:
  50 #       headers add "X-Vygo-Net-Temporary-Message-Id: <${local_part:$h_Message-Id:}@${lookup{${domain:$h_Message-Id:}}lsearch{/var/exim/msgid-hosts}{$value}{${domain:$h_Message-Id:}}}>\n"
  51 # This rewrites Message-Id as <local_part.domain@unique.domain>:
  52         headers add "X-Vygo-Net-Temporary-Message-Id: <${local_part:$h_Message-Id:}.${domain:$h_Message-Id:}@unique.remote.dom>\n"
  53         headers remove "Message-Id"
  54         headers add "Message-Id: $h_X-Vygo-Net-Temporary-Message-Id:"
  55         headers remove "X-Vygo-Net-Temporary-Message-Id"
  56 endif
  57
  58 # Change Resent-Message-Id:
  59 if "${if def:h_Resent-Message-Id: {yes}}" is yes and
  60     ${lc:${domain:$h_Resent-Message-Id:}} is    "home.dom" or
  61     ${lc:${domain:$h_Resent-Message-Id:}} ends ".home.dom" then
  62 # This is if you want to have a file mapping each hostname to a unique
  63 # Message-Id domain part, or, if it fails, preserves the original domain part:
  64 #       headers add "X-Vygo-Net-Temporary-Message-Id: <${local_part:$h_Resent-Message-Id:}@${lookup{${domain:$h_Resent-Message-Id:}}lsearch{/var/exim/msgid-hosts}{$value}{${domain:$h_Resent-Message-Id:}}}>\n"
  65 # This rewrites Message-Id as <local_part.domain@unique.domain>:
  66         headers add "X-Vygo-Net-Temporary-Message-Id: <${local_part:$h_Resent-Message-Id:}.${domain:$h_Resent-Message-Id:}@unique.remote.dom>\n"
  67         headers remove "Resent-Message-Id"
  68         headers add "Resent-Message-Id: $h_X-Vygo-Net-Temporary-Message-Id:"
