FRITZ!Box 6590 Cable 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, configuration data, no messages from its internal answering machine, and no 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 use special security mechanisms to protect their email accounts that prevent push service mails from being sent:

Adjusting your Google account settings

  1. If you enabled the 2-step verification method for your Google account, generate anapp password for the FRITZ!Box and use it when setting up the email account.

Adjusting your Microsoft account settings

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

Adjusting your Apple account settings

  1. If you enabled the 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 require you by default to use webmail instead of allowing you to use email clients to send email:

  1. Enabling use of external email client 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 the "Configure Push Service" link. If the link is not shown, click on the "Sender" tab.
  4. Enter your email address and password.
  5. Click "Account Information - Additional Settings".

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

  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 in the "Port" field, for example 587.
  8. If the server supports SSL, enable the option "This server supports a secure connection (SSL)".
  9. Enable the option "Test email sending after adopting the settings". If the option is not available, the test email will be sent automatically.
  10. Click "Apply" or "Next" and follow the wizard's instructions.
  11. Now the FRITZ!Box sends a test email to your email account.

4 Contacting your provider

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

  1. Contact your email provider.
