FRITZ!Box 7340 Service

Push service mails are not sent

Although the push service was configured according to our guide, the FRITZ!Box does not send any emails with connection data, usage data, or configuration data, nor does it send 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."

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Adjusting the email account settings

Many providers protect their email accounts with special security mechanisms that prevent push service mails from being sent:

Adjusting Google account settings

  1. If you enabled 2-Step Verification for your Google account, create an app password for the FRITZ!Box and use it to set up the email account.

Adjusting Microsoft account settings

  1. If you enabled two-step verification for your Microsoft account, create a new app password for the FRITZ!Box and configure this as the password for the push service.

Adjusting Apple account settings

  1. If you enabled two-factor authentication for your Apple ID, set an app-specific password for the FRITZ!Box and configure this as the password for the push service.

2 Enabling email sending in your email account

Some providers have email sending via a different program switched off by default:

  1. Enable the use of external email clients in your email account.

    Note:With some providers, you can enable this in the settings for POP3/IMAP access.

3 Correcting email account information in the FRITZ!Box

This error is often caused by incorrect email account information, for example an incorrect password. Therefore, enter this information again:

  1. Click "System" in the FRITZ!Box user interface.
  2. Click "Push Service" in the "System" menu.
  3. Click on the "Sender" tab.
  4. Enter your email address and the password.
  5. Click "Account Information: Additional Settings".

    Note:In most cases, the FRITZ!Box fills in the following information automatically. With smaller local providers, you have to enter it yourself. The required information can be obtained from your email provider.

  6. Enter your user name and the name of your email provider's SMTP server.
  7. If the server cannot be reached over port 25, enter the port used by the server to communicate, for example 587 (see fig.).
  8. If the server supports SSL, enable the option "This server supports a secure connection (SSL)".

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

    Important:Save the settings first and then click "Testing Push Service" or "Test Settings". Otherwise, the data will not be adopted correctly.

4 Contacting your provider

If the test email was not sent, your account information is incorrect or there is a problem with your provider:

  1. Contact your email provider.
