Setting Up Email Client

You can access and send your email via webmail or using an email client like Mozilla Thunderbird, MS Outlook, or Apple Mail.

In the following example, we will configure the Thunderbird email client. Follow these steps:

• Select File -> New -> Existing Email Account from the menu
• Enter your name, email address, and the associated password. You can find the connection data in your Control Panel ¹
• Click Next. Thunderbird will now attempt to automatically detect the settings ²

If the error message “Thunderbird could not find settings for your email account” appears, please check and correct the following fields:

• Server name: Enter the server name
• IMAP Port (STARTTLS): Choose the IMAP protocol with port 143 for incoming mail

If you prefer to use SSL/TLS instead of STARTTLS, select port 993 for the IMAP protocol for incoming mail.

Incoming and outgoing mail use separate protocols and must be configured correctly for both.

Outgoing Mail

To configure the outgoing mail server, go to Edit -> Account Settings, then click on “Outgoing Mail Server (SMTP)”. There should already be an entry, which may not have been automatically detected and needs to be adjusted accordingly.

• SMTP Port: Choose port 587 for outgoing mail
• Authentication: Set the authentication to “Password, normal”
• Click “Done”

Instead of the default server port 587, you can also set SSL with port 465.

In Thunderbird, the port will be set automatically when you change the SSL or STARTTLS selection.

Choose the solution appropriate for your software setup.

The servers support both SSL and STARTTLS. Depending on the client, one setting might work better than the other.

Please restart Thunderbird after setup.
