How do I set up my email address in Apple Mail?

Your login details at a glance

Setting	Value
Incoming mail server (IMAP)	oberon.jumpit.eu · Port 993 · SSL/TLS
Outgoing mail server (SMTP)	oberon.jumpit.eu · Port 587 · STARTTLS
Username	Your full email address (e.g. info@mycompany.com)
Password	Your email password

Important: The server is always oberon.jumpit.eu, not your own domain name. This is the most common mistake during setup. The outgoing mail server (SMTP) requires authentication with the same login details as the incoming server.

Step by step

1. Open Apple Mail on your Mac.

2. In the “Mail” menu at the top left, click “Settings”.

3. Select the “Accounts” tab and click the ”+” symbol to add a new account.

4. Choose “Other Mail Account” and click “Continue”.

5. Enter your name, the email address and the password for the account. Then click “Sign In”.

6. Choose “Configure account manually” and click “Next”.

7. Choose “IMAP” as the account type.

8. Enter oberon.jumpit.eu as both the incoming mail server and the outgoing mail server (not your own domain name).

9. Use your full email address as the username, plus your password.

10. Click “Next”. Apple Mail establishes the connection; encryption (SSL/TLS) is used automatically.

11. If the ports are requested or the connection doesn’t work, check under “Mail → Settings → Accounts → Server Settings”:

    • Incoming (IMAP): server oberon.jumpit.eu, port 993, TLS/SSL enabled
    • Outgoing (SMTP): server oberon.jumpit.eu, port 587, STARTTLS, authentication with email address and password

12. Choose the sync options you want and click “Done”.

Once you’ve followed these steps, Apple Mail is connected to the IMAP and SMTP server. You can now send and receive emails.

Login not working?

If the connection fails, it’s almost always down to one of these two things:

• Wrong server: It has to be oberon.jumpit.eu, not your own domain.
• Wrong password: Check your email password directly in webmail. To do so, open https://webmail.yourdomain.xyz (replace “yourdomain.xyz” with your own domain, e.g. https://webmail.mycompany.com). There you can log in to test whether your login details are correct, and reset the password via “Forgot password” if needed. More in the article Test or change email password.

Note: The exact labels may vary depending on your macOS version. The server, ports and encryption always stay the same, though.
