Configure Thundermail for Thunderbird Desktop

1. Click the Thunderbird menu ☰ > Add Account (New Account for older versions of Thunderbird) > Email.
2. Enter your Thundermail email address and follow the prompts to set up your Thundermail email account. And for versions older than 150, please click the Connect button next to Thundermail Address Book and the Connect button next to Thundermail Calendar to ensure your Thundermail address book and calendar are added to Thunderbird.

Thunderbird should have automatically added your Thundermail email in account settings, a CalDAV calendar called Thundermail Calendar in your Thunderbird calendar space (press Alt + 3Ctrl + 3), and a CardDAV address book called Thundermail Address Book in your address book space (press Alt + 2Ctrl + 2) to check). If any of those are missing, please try changing the settings to those in the manual settings sections below, and please create a Thunderbird Pro support ticket if you have any issues.

Manual Settings

If Thunderbird failed to add the expected items or you need to adjust them, please try manually changing the settings by following the instructions in the sections below. If manual setup fails, please create a Thunderbird Pro support ticket.

Custom Domain catch-all and custom aliases

How to setup Thunderbird Desktop for custom domains in Thundermail:

Send and receive email with Thundermail custom domain aliases using Thunderbird identities

For every custom domain alias you create in Thundermail, you will have to create a new identity in Thunderbird in order to send email with that alias. Here's how using our example custom domain glamroc.com, our example Thundermail address of roc@thundermail.com, and custom domain alias of roc@glamroc.com:

1. Click Thunderbird app menu ☰ > Account Settings > Click on the thundermail.com account in the left sidebar which in our example is: roc@thundermail.com > Manage Identities…" > Add….
2. Add your custom domain alias e.g. roc@glamroc.com by filling in the New Identity form, and then click OK when you are done.
3. If you want this to be the default identity when composing new email, click on the new identity, and then click on Set Default and Close.

Now the custom domain alias, roc@glamroc.com is the default identity when writing new email and you can send and receive email on both roc@thundermail.com and roc@glamroc.com by selecting the appropriate identity.

Send and reply to email using a Thundermail catch-all alias

• If you have a catch-all alias configured in Thundermail for a custom domain, here's how to use it:
  1. When composing or replying to an email, click on the email address next to From.
  2. Click on Customize From Address….
  3. Finally, type in an email address for the custom domain you created the catch-all in.
