Laptop or desktop mail setup

Mozilla Thunderbird is a popular mail and calendar program. It is open source and free to download and use. It comes pre-installed on Nikhef desktops, but requires some personal configuration. It can easily be downloaded and installed on personal devices.

Thunderbird comes pre-installed on Nikhef desktops and managed systems. For personal devices (laptops) the instructions depend on operating system. Download the Linux, macOS, or Windows packages from

After opening the installed Thunderbird application:

  1. Choose to Setup an existing email account (this is automatic on first use).
  2. Fill in Full name, (Nikhef) email address and your Nikhef password. Thunderbird should automatically discover the incoming and outgoing servers and any address books and calendars linked to the account.

For manual configuration, use these values:

  • Incoming/IMAP mail server:, port: 993, SSL/TLS with password;
  • Outgoing/SMTP server:, port: 465, SSL/TLS with password.
Do not synchronize your mail to your computer!

For installations on Nikhef desktops, you have to disable automatic synchronisation of email to your computer, as it will use up all your disk quota in your home folder.

To do this:

  1. Go to Account Settings;
  2. Go to Synchronization and Storage in your account;
  3. Uncheck the Message Synchronizing box.

For personal devices (laptops) this is not an issue, but be aware of sensitive data when storing mail locally. (note that a laptop used for Nikhef should have full-disc encryption).

How to enable Thunderbird to check for new messages in other folders

If you are using multiple folders on the IMAP server to structure your email, then you might experience the problem that new messages in subfolders are not updated automatically upon refresh of the Inbox. You can change a folder's properties to automatically check the folder when synchronising new messages. The folder properties are found under the context menu (right click on most systems).

Other mail accounts

Thunderbird can be used to manage multiple mail services, such as Gmail, from within one program. For instructions see

Mobile phone client setup

These instructions are based on the (open source) K-9 Mail app and the OpenSync app for Android.
