Settings for Thunderbird

Thunderbird is a free/libre e-mail client available for Linux, macOS and Windows. You can also use it to manage your calendars, tasks and contacts.

You can download the software via the website of Thunderbird.

E-mail icon E-mail

Follow these steps → Automatically configure your account [↗ Help from Thunderbird]1. Use the login data which are mentioned here below.

(Semi-)Automatic configuration

Connection information

  1. Use your email address and Nubo password
  2. If you need to enter a server, use mail.nubo.coop
I have to choose between IMAP and POP3. What are they?

Many software packages offer the option of configuring mailboxes as "IMAP" or "POP3".

  • With IMAP, the contents of your entire inbox, including folders and sub-folders, as well as the various message statuses (read, unread, marked, replied to, forwarded...) are synchronized between your devices, so a change on one is reflected on the others.
  • With POP3, your software simply retrieves new messages from the inbox, without taking care of anything else, and deletes them at regular intervals, making them inaccessible on other devices, and deleting them from your webmail.

IMAP is more recent and is the recommended option.

I am being asked for several names (name, account name, full name, user name…). What should I do?

During configuration, you are often asked to enter the name of the person who will use this mailbox. This option can be called "name", "displayed name", "full name", "your name"... This field is free-form, you just have to enter what you want your correspondents to see when they receive your messages.

If you're asked for a "username", then this is the username associated with your account, so you'll need to re-enter your e-mail address (or your Nubo username - both should work).

If you see "account name" or "description", this is again a free-form field which will let you identify the account in the interface of the software or the application you are setting up.

Manual configuration

If that doesn't work, or you need to enter the information yourself, use the parameters below.

Full configuration information
Incoming (receive) Outgoing (send)
Protocol IMAP (or POP3) SMTP
Server mail.nubo.coop mail.nubo.coop
Port 993 465
SSL SSL/TLS SSL/TLS
Authentication Regular password Regular password
Identifier (user name) Your email address Your email address

Cloud icon Cloud

As an option, Thunderbird offers the ability to automatically use the cloud to attach files to messages.

Why use the cloud for e-mail attachments?

There are several advantages:

  • Some servers don't accept large files. Even if you manage to send your attachments, your recipients may not receive them.
  • If you do not use the cloud for attachments, they are stored together with your messages in your mailbox, as well as in the mailboxes of your recipients. Moreover, they travel along with your message all the way to its destination. By using the cloud, the file is only in one place and will not be copied unnecessarily, saving energy and resources on all servers and on mailbox disk space.
  • Your recipients download the file from the cloud only when they need it.

Follow these steps → Filelink for large attachments [↗ Help from Thunderbird] avec les informations ci-dessous.

Use these login credentials

  1. The add-on to be installed is "*cloud - FileLink for Nextcloud and ownCloud"3.
  2. Enter https://cloud.nubo.coop as server address
  3. Use yoru Nubo ID as user
  4. Make a app password as your password
Other Settings

In the preferences of Thunderbird ("Preferences > Settings > Attachments"):

  • You can lower the value of "Propose sharing for files larger than ... MB" to 1 or 2 if you want to use the cloud more systematically.
  • In the advanced options, you can change the name of the cloud folder to which attachments will be sent (default: "Mail-attachments"), e.g. enter "Attachments" in the "Path to remote folder" field.
  • As soon as the account is added, you can change its name by clicking on the name. (default is "*cloud") in the list, Call it for example "Cloud Nubo"

  • Add-ons are sometimes called "Extensions."
  • All add-ons that are recommended here can be installed using "The ideal situation" method.
To make an app password

Passwords software enable external applications to be connected using unique passwords.

You can create them and manage them yourself from your cloud.

  1. Open the page 'Security' of your cloud
  2. Enter the app name (at the bottom of the list of devices and sessions recently connected to your account)
  3. Click on 'Create a new app password'
  4. Write down or copy the password displayed, you won't be able to see it after.
  5. Click on 'Finished'
Good to know

When you are creating an app password

  • Give your application a recognisable name, so that you can find it easily in the list of connected sessions.
  • If you did not copy the password, delete the application from the list and start over
  • The QR-code only works with certain application who offer this option when enter login informations

Possible options

Click on the '…' next to an element of the list to display the options - 'Revoke': delete the element from the list, the device or the app will not have access to you account anymore - 'Delete the device' : start a process to erase your data from the application in question - If the application you are configuring does not need access to your files, deselect "Allow access to file manager".

Practical:

  • You will always be asked for confirmation, when you want to place attachments in the cloud. The options appear automatically when you join files as attachments. By clicking "link" a copy will be placed on the cloud and an insert with a link will be added to your message.
  • As is explained on this page [↗ Help of Thunderbird], you can always force an attachment so that it is put in the cloud, or as alternative, supress the link and send the document as attachment.
  • You can change the automatic insert in the message with the link to the attachments on a case-by-case basis. Currently, it is not possible to change the default template.
  • If you like to use passwords for file sharing, and therefore if your attachments contain sensitive data, don't send the password along with the message, but communicate it to your recipient in another way (phone, other messaging service, etc.).

App Agenda App Taken App Contactpersonen Agenda, taken en contactpersonen

There are several ways to integrate calendars (with associated tasks) and contacts into Thunderbird.

The method depends on the version of Thunderbird you have.

How do I find the version of Thunderbird?

Go to the "Help" menu and click on "About Thunderbird" (if you don't see the "Help" menu, click on "≡" top right in the Thunderbird window).

You will find a series of numbers, seperated by points, such as: XX.XX.X. The first two numbers are the most important ones. The latest versions of Thunderbird are 91.0 and 78.0. 2.

Thunderbird 91

Starting from version 91, which appeared in the summer of 2021, Thunderbird has an option to synchronise your contacts (CardDAV). Together with the already existing options to synchronise camendars (CalDAV), Thunderbird makes it possible to manage contact persons and calendars from the cloud.

Integration of contact persons (native)

No synchronisation of groups with contact persons in Thunderbird 91

The integration of synchronised contacts in Thunderbird 91 does not allow for managing groups (or catagories) with contact persons. If you want to keep groups as you see them in the Contactpersons tab in your cloud, follow the procedure in "Only Contactpersons (CardBook)" which you will find further on on this page. (in methods for Thunderbird 78). — If you know anpother solution Please let us know. Thank you!

To add contact persons to the cloud in Thunderbird:

Login credentials

  1. Use your Nubo ID as username
  2. Make an app password as a paswword
  3. Enter cloud.nubo.coop as address
  • Ope your address book : click on the icon in the menubar or go to the menu : "Tools > Address book" (if you do not see "Tools", click on the "≡" top right in the Thunderbird window)
  • Go to "File > New > CardDAV-address book..."
  • Enter your Nubo ID as user name
  • Enter cloud.nubo.coop as address
  • Make an app password and enter it as your password.
  • Choose the address book(s) that you wish to synchronise

Practical :

  • Thunderbird saves local address books ("Personal Addresses" and "Collected Adresses"), so make sure that you add new contacts to the correct book. If you did not change it from within the cloud, the address book in the Nubo cloud is called "Contacts".
  • Address books are synchronised every 30 minutes. right click on the address book and choose "sync" if you want to carry out an immediate sunchronisation.
  • You can change the name of the address book (e.g. "Nubo Contacts") by right-clicking on it and choose "Propoerties". Ths name change will only be visible within Thunderbird.

Integration of calendars (native)

Follow these steps → Make a new calendar [↗ Help of Thunderbird]. Use the login credentials that are following here after.

Use these login credentials

  1. Choose making a new calendar "on the network".
  2. Use your Nubo ID as user name
  3. Enter cloud.nubo.coop as address
  4. Make a app password and enter it as your password

Practical:

  • Thunderbird has a default calendar ("My Calendar") that is disabled. This calendar is local (on your computer) and is not linked to your cloud. It will never be synced.
  • Calendar synchronization happens every 30 minutes. Right-click in the list and choose "Synchronize calendars" if you want to force an immediate synchronization.
  • You can change the properties of calendars at any time by double-clicking on them (or right-clicking and choosing "Properties"). These changes, such as names or colors, will only be visible in Thunderbird.
