FRITZ!Box 7340 – Service

Push service mails are not

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:

  • "E-mail delivery failed: SMTP server reports [...]"
  • "E-mail delivery failed: TCP error"
  • "Sending of an e-mail message failed. Reason: authentication error."
  • "Sending of an e-mail message failed. Reason: TCP error."


  • The SMTP server entered in your FRITZ!Box for your e-mail provider does not respond to the connection request sent by the FRITZ!Box, for example due to incorrect account information or because your e-mail 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 e-mail account settings

Many providers employ special security mechanisms to protect their e-mail 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 e-mail account

To retrieve your e-mails, you must use an e-mail account with a POP3 e-mail server, and POP3 download must be enabled with your e-mail provider:

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

3 Setting up e-mail account information for push services

  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 e-mail account in the "E-mail user name" field.
  6. Enter the password for your e-mail account in the "Password" field.

    Important:The password for your e-mail 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 e-mail 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 e-mail is sent to the e-mail address you entered.
