Setting up email programs and apps: Activating POP3 / IMAP / SMTP access
Access for email programs (POP3, IMAP, SMTP) is disabled by default in eclipso Mail Europe for security reasons. You need to enable it once in your webmail account before you can connect your email program or app.
Security note: By disabling client access by default, your account is protected even if your password falls into the wrong hands. An attacker may be able to log into webmail, but cannot retrieve or send emails via external programs or scripts – as long as you have not actively enabled access.
Why is POP3/IMAP/SMTP access disabled by default?
Automated attacks on email accounts often target SMTP connections directly to send spam or phishing emails from hijacked accounts. By disabling access by default, eclipso Mail Europe protects you and other recipients from this type of abuse. Activation requires a deliberate one-time action in webmail – this ensures that only genuine users can set up access.
What are the requirements?
- You need an active eclipso Mail Europe account.
- You must log in once via webmail (www.eclipso.eu/login) to enable access.
- Activation is free of charge and available for all plans without restrictions.
How to enable POP3/IMAP/SMTP access:
- Log in to your eclipso Mail Europe account: www.eclipso.eu/login
- Open the menu Settings › POP3/IMAP/SMTP
- Click the button Enable access for email clients
- The activation takes effect immediately. You can now set up your email program.
Connection settings for email programs
After activation, use the following settings in your email program (e.g. Microsoft Outlook, Mozilla Thunderbird, Apple Mail):
| Incoming mail server (IMAP): | mail.eclipso.de Port 993 (SSL) |
| Incoming mail server (POP3): | mail.eclipso.de Port 995 (SSL) |
| Outgoing mail server (SMTP): | mail.eclipso.de Port 465 (SSL) |
| Username: | Your full email address |
| Password: | Your eclipso password |
| Authentication: | Password, normal |
Disable access again
If you no longer use an email program or want to further secure your account, you can disable access at any time:
- Settings › POP3/IMAP/SMTP
- Click Disable access
Tip: If you use email exclusively via the web interface or our app, we recommend keeping client access disabled. This additional step protects your account against unauthorized access.Related articles:
