Creating restricted email lists on ISC Networking mail servers

  • Create a directory called alias in your account's home directory.
    Enter the UNIX environment and type
    • cd
    • chmod a+x .
    • mkdir alias
    • chmod a+x alias
    Note that the "chmod" command opens up the directory so that the system's mailer can read it.

  • In the "alias" directory, create a file called list-name.list, where you replace "list-name" with the name of your list. This file will designate who receives copies of email sent to the distribution list. If you were creating a list named "penn-zen", enter the UNIX environment and type
    • cd alias
    • pico penn-zen.list
      Type in the recipients' email addresses. There should be only one email address on a line and you must type in the full email address. Save the file, exit PICO, and you'll return to the Unix prompt.

  • With a restricted list, only the owner of the list and people authorized by the owner of the list may send messages to the list. The owner of the list is automatically authorized to send mail to the list. If no other people need to send mail to the list, you can skip this step.
    If you wish to allow other email addresses to send mail to your list, in the "alias" directory, create a file called list-name.sender, where you replace "list-name" with the name of your list.
    If you were creating a list named "penn-zen", enter the UNIX environment and type
    • cd alias
    • pico penn-zen.sender
      Type in the email addresses of the people you wish to authorize to send to your list. There should be only one email address on a line and you must type in the full email address. If you want to allow all users on your list to post messages, then place *members on one line in your listname.sender file.
      Save the file, exit PICO, and you'll return to the Unix prompt.

  • Now you are ready to submit the request.
    From the unix prompt or from the main menu, type
    • list-menu
      and choose the "add a restricted distribution list" option.

  • When requesting an restricted distribution list, you will be given an electronic submission form and asked to fill in two fields:
    • List name
      This is the name that you choose for your list. For example, if you type "penn-zen" here (do not include the quotes), the address of the distribution list would be
      penn-zen@pobox.upenn.edu
      Remember that only lowercase letters, numbers and dashes - or underscores _ are allowed in this field. Try to keep this field short -- your members may find a long name annoying.
    • List purpose
      Just a short description here of what you plan to use the list for. There is no need for more than a few words here. "For the exec board" would suffice.
      Note that if you already own an unrestricted distribution list with the same name, you will be prompted to delete the unrestricted distribution list before continuing. This is an automatic process and you do not have to submit a deletion request for this unrestricted distribution list.

  • If you make any changes to either the listname.list or sender.list file, you must update your list.
    From the unix prompt or from the main menu, type
    • list-menu
      and choose the "update a restricted distribution list" option.

    If you have any questions, contact local support provider.
