FRITZ!Box 7340 Service

Push service mails are not sent

The FRITZ!Box cannot send push service mails with connection data, usage data, configuration data, messages from its internal answering machine or faxes from its internal fax server.

One of the following error messages is displayed in the event log of the FRITZ!Box:

  • "Email delivery failed: SMTP server reports [...]"
  • "Email delivery failed: TCP error"
  • "Sending of an email message failed. Reason: authentication error."
  • "Sending of an email message failed. Reason: TCP error."


  • The SMTP server entered in your FRITZ!Box for your email provider does not respond to the connection request sent by the FRITZ!Box, for example due to incorrect account information or because your email provider is experiencing technical difficulties.

Note:The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS for your FRITZ!Box.

1 Adjusting the email account settings

Many providers employ special security mechanisms to protect their email accounts. They may also prevent push service mails from being sent:

Adjusting your Google account settings

Adjusting your Microsoft account settings

Adjusting your Apple account settings

2 Enabling POP3 download in your email account

To retrieve your emails, you must use an email account with a POP3 email server, and POP3 download must be enabled with your email provider:

  • Enable POP3 download in your email account settings. Your email provider can provide you with information on the procedure.

3 Correcting email account information for push services

This error is often caused by incorrect email account information, for example an incorrect password for your email account. Therefore, you must check the information you entered:

  1. Click "System" in the FRITZ!Box user interface.
  2. Click "Push Service" in the "System" menu.
  3. Click on the "Sender" tab.
  4. Click "Account Information - Additional Settings".
  5. Enter the user name for the email account in the "Email user name" field.
  6. Enter the password for your email account in the "Password" field.

    Important:The password for your email account is not the same as the password required to access your personal customer account data.

  7. Enter the SMTP server in the "SMTP server" field. If the SMTP port is not accessible over port 25, then you must also enter the port used by the server to communicate (for example 587, see fig.). Your email provider can tell you what to enter for the SMTP server.
  8. Enable the option "This server supports a secure connection (SSL)" if the server supports it.

  9. Click "Apply" to save the settings.
  10. Click "Test Settings" in order to test whether you entered the account information correctly.

    Important:First click "Apply" to save the settings, and then click "Test Settings" or "Testing Push Service" afterwards, as the information you entered will otherwise not be applied correctly.

    • A test email is sent to the email address you entered.
