## Unable to connect through sending email address host name

##### Symptom

The appliance is not able to send alert messages using the configured email address.

### Invalid configuration parameter

##### Cause

One or more parameters for configuring email notification is invalid, preventing the appliance from reaching the host used for sending email.

1. As Infrastructure administrator, follow the procedure in Configure the appliance for email notification of alerts so that you can view the configuration parameters.

   For more information on these parameters, see Edit Notifications screen details.

2. Correct any invalid configuration parameter.

3. Save the configuration.

4. Verify the configuration either by pinging the host or by sending a test message.

### Appliance cannot access the network

##### Cause

The appliance is experiencing network issues, which prevents the appliance from sending email messages.

##### Action

1. As Infrastructure administrator, verify that the host name for the sending email address is on the network by pinging the host.

2. See Appliance cannot access the network to resolve problems connecting with the network.

## Host does not respond as an SMTP server

##### Symptom

The host name, which should send the email messages, is not responding as an SMTP server.

### Invalid configuration

##### Cause

The host name was not configured correctly.

##### Action

1. As Infrastructure administrator, verify that the host name for the sending email address is on the network by pinging the host.

2. Verify the port number used is correct.

3. Follow the procedure in Configure the appliance for email notification of alerts so that you can view the configuration parameters.

4. Update the Email parameters as needed.

5. Save the configuration.

6. Verify the configuration with the `telnet` command. For example:

       telnet mail.example.com 25

7. Verify also by monitoring email notifications.

### SMTP server with TLS/SSL security protocols

##### Cause

The SMTP server used for sending email notification has TLS/SSL security protocols.

       telnet mail.example.com 25

6. Verify also by monitoring email notifications.

### Invalid password

##### Cause

The email notification configuration has an invalid password for the SMTP server. The email cannot be sent because it fails to provide the correct authentication.

##### Action

1. Use the `telnet` command to connect to the SMTP server to verify the password. For example:

       telnet mail.example.com

2. See Configure the appliance for email notification of alerts to learn how to view the configuration parameters.

3. Ensure that the SMTP server password is correct.

   Update the Email parameters as needed.

## Email notifications not being received by all recipients

##### Symptom
