Push service mails are not sent
Although the push service was configured according to our guide, the FRITZ!Box does not send any emails about the status of your smart home devices. 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.
Simply proceed as described below. After each measure, check whether the problem is solved.
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
- Generate an app password for the FRITZ!Box and configure it is the password for the push service.
Adjusting Microsoft account settings
- 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
- 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.
Adjusting Yahoo account settings
- Generate a new app 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:
- 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
Incorrect email account information, for example an incorrect password, is often the cause of this error. Therefore, enter this information again:
- Click "System" in the FRITZ!Box user interface.
- Click "Push Service" in the "System" menu.
- Click the "Configure Push Service" link. If the link is not shown, click on the "Sender" tab.
- Enter your email address and password.
- Click on "Account Information: Additional Settings".
Note:In most cases, the FRITZ!Box automatically completes the following information. With smaller local providers, you have to enter it yourself. The required information is supplied by your email provider.
- Enter your username and the name of your email provider's SMTP server.
- If the server is not accessible on port 25, enter the port used by the server to communicate in the "Port" field, for example 587.
- If the server supports SSL, enable the option "This server supports a secure connection (SSL)".
- Enable the option "Test email sending after adopting the settings". If the option is not available, the test email will be sent automatically.
- Click "Next" or "Apply" and follow the wizard's instructions.
4 Contacting your provider
If the test email was not sent, your account information is incorrect or there is a problem with your provider. With some email providers, an additional password must be set up in the customer portal or the provider protects the email account with additional security mechanisms, for example:
- Contact your email provider.
