Mailing lists

We have two types of mailing lists:
  • The mailing group addresses derived from the Beaufort database as maintained by the Personnel Department (PZ) at Nikhef.
  • The Mailman lists maintained by the owner (you) via a web-based interface.

Mailing group addresses

The group addresses are updated nightly with the actual information from the PZ database. The name scheme of these group addresses is derived directly from the PZ database. Addresses are grouped by organic units (like departments and programmes) and by type of employment (like Scientific Staff and OIO/AIO).
When a new group is "made" in Beaufort, it will generate a new group in LDAP. Automagical.
Examples of organic units:
mailing group address name organic unit
group-astroparticle-physics Astroparticle Physics
group-ct Computer Technology

Examples of type of employment:

mailing group address name type of employment
group-oio-aio-aanstellingen OIO/AIO Aanstellingen
group-op-v-aanstellingen Overige Personeel Vast Aanstellingen

Find all group addresses:

You can list all entries in a group address as follows:

  1. Go to the Single-Sign-On page
  2. Follow the link 'Resolve email addresses' on the menu at the left side of the page.
  3. Enter your account name and password.
  4. Type the name of the email address you want to resolve (e.g. group-oio-aio-aanstellingen).
  5. Click the 'List destination addresses'.

Mailman lists

How does it work?

CT sysadmin supports Mailman type mailing lists.

In case you want to set up a mailman list, request the CT helpdesk to create one for you. You will become the owner of the list and you will get access to a web interface to manage the list.

Being the owner of a mailing list you can configure all kind of attributes:

  • add or delete members
  • give or deny others the right to send to the list
  • maintain archives of all mails sent to the list
  • and many more.

Using group addresses in mailman lists

It might be handy to add mailng group addresses as members of a mailman list.

Consider you are leading a group and you want to setup a mailman list with members not only the employees in your group (according to PZ), but also with members who are somehow connected to your group, like students, external persons, former members or whatever. The following is an example the mailman member list

group-atlas at
wilhem.tell at
j.l.hooker at at at

Another example is the mailman list, its member list looks like this:

phys-all at
tech-all at
supp-all at
Note: In case you do not want to use mailman lists for some reason, there is an alternative. It is possible to add static e-mail addresses to the dynamic group addresses. This requires CT helpdesk support.

In case you own a list and want to do membership administration or list configuration, do the following using your web browser:

Type 'mailman' (at Nikhef) or '' 
The mailman list overview page will appear
Select your list and click on it
On the next page follow the link on the bottom of the page: 'xxxx administrative interface'
Enter your password
Start doing your administration, like membership management or whatever.

Limiting senders to post to the list

Limiting the group of senders to the list, e.g. only members of the list are allowed to send mail to the list, prevents spam mail to the list address be delivered to the members.

Example, allow only users in the domain post to the list:

Privacy Options -> Sender Filters -> List of non-member addresses whose postings should be automatically accepted
Enter Python regular expression: ^.*

Accept posts to the list from non-members

To accept posts from non-members (the whole world) configure the following:

Privacy Options -> Sender Filters -> Action to take for postings from non-members for which no explicit action is defined. 
Enable Accept button.
