IT Services is decommissioning Mailman, which has been used in 2 ways at Sussex:
We are replacing Mailman with two services that provide most of the same functionality, and in many cases offer new features.
We realise this change will cause some disruption to the way you work, and we hope that the resources on this page will allow you to transition smoothly to the new technologies.
As the last year has proven, the University depends on a stable, adaptable and future-proof technological foundation. We were able to pivot to online learning so quickly because ITS had been moving towards cloud-first solutions for the last few years.
In order to provide the kind of capabilities that we want to deliver in the future, and in order to provide the level of security that’s expected within our sector, we have examined every piece of hardware and software within our estate. Older systems that can’t meet these demands are being replaced and phased out.
Unfortunately, Mailman is one of these platforms. It is a specialist, focused system that’s designed to do one job, and it does that very well. However, despite our best efforts we haven’t found a way to make it fit within the modern suite of platforms and technologies that we are adopting as we modernise the University’s IT estate. If we want to enhance our security further, and if we want to offer wider features in the future, it must be retired.
Our approach has been to consider the way that Mailman is used, and then find solutions that already exist within the Microsoft suite.
If you have used Mailman to send bulk emails, perhaps to a school, department or the whole University, then your replacement is a system that already exists within our email system, called Distribution Groups.
If you own a Mailman list of this type, and if you replied to our recent survey, then your list is being turned into a Distribution Group.
You can access Distribution Groups via Outlook Online (outlook.office.com, the web-based email client you have probably used before).
Your members won’t notice any change when they receive messages. The message will come from the same address.
To email your members, just compose an email and put the list address in the To field (or the BCC field, if you don’t want your recipients to be able to see and contact all members of the Group).
You will be able to find your list in the address book if you can’t remember the exact name.
By default, only owners can do this. If somebody else tries to email your group, you will be sent an email asking you to moderate this message. This setting can be easily changed, if you want to allow some senders - for example group-members - to email the list without moderation
Visit outlook.office.com, log in if necessary using your username@sussex.ac.uk, then click on the cog icon in the top right corner. Click in the search box and type Distribution, then click on the option for Distribution groups.
Here, you can edit lots of settings, and you can add/remove members.
For more details, please see Microsoft’s guide about using Distribution Groups.
If you have used Mailman to hold conversation threads, then your replacement is mail-enabled Microsoft Teams.
You can continue to use these as email distribution lists, so any member can email the list and everybody will receive the message. The email address of the list will remain the same.
However, if you want to make use of the Microsoft Teams application (which is becoming the standard platform for chat, file sharing and collaboration between staff the University) you can do this too. All members of your list will also be members of the Team when they next open the Microsoft Teams application.
In Microsoft Outlook (either the web version at outlook.office.com, or Outlook on your computer), there is a list of Groups in the left hand pane, under all your accounts and folders. Scroll down to the Groups section and you will find your new inbox.
From here, you can compose new messages to the group, review messages from other members, or (if you are the owner) change the settings for the list.
Teams is quickly becoming one of the core applications used at Sussex. Staff use it every day to chat, call, share files, or collaborate live online. If you used Mailman as a method to have conversations, you will find a new Team within Microsoft Teams with the same name as your old list. You can begin using this right away, or you can continue using the email method explained above. Or you can use both. It’s up to you and your members.
If you are new to Microsoft Teams, you can:
