Understanding Custom Email Servers

Cloud Assess allows organisations to configure a custom SMTP server to send system-generated (or custom) emails using their own email domain. This can improve email deliverability and maintain brand consistency.

Scope

This article explains how to configure a custom email server within Cloud Assess.

Requirements

You will need the following information from your IT team or email administrator:

  • SMTP server address (host name)

  • SMTP port number

  • Encryption method (TLS or SSL)

  • Username for authentication

  • Password or application-specific password

  • Sender email address

Note: You must be a Power user within Cloud Assess to update the Custom Email Server settings.

Configure the Email Server

  1. Log in to Cloud Assess using a Power user account.

  2. Navigate to Settings.

  3. Select Other Apps under Integrations

  4. Manage Custom Email Server.

  5. Enter the required SMTP details:

Field

SMTP Server Address

The address of your outgoing mail server. A quick Google search can help find this detail - based on your email client e.g. Outlook.

Port

The port used for SMTP communication

Username

The email account used for authentication

Password

The password associated with the account

Security

Select the required security protocol (TLS/SSL)

Authentication

6. Review the information entered to ensure it is correct.

7. Select Save to apply the configuration.

Test the Configuration

After saving the settings, it is recommended that you perform a test to confirm that emails can be sent successfully.

Common SMTP Settings

The exact settings required will depend on your email provider. Your IT team should provide the correct values for your environment.

Common SMTP ports include:

Port

Typical Use

25

Standard SMTP (often restricted)

465

SMTP using SSL

587

SMTP using TLS (recommended)

Troubleshooting

Authentication Failed

If you receive an authentication error:

  • Verify that the username and password are correct.

  • Check whether the email account requires an application-specific password.

  • Confirm that SMTP authentication is enabled for the account.

Emails Are Not Being Delivered

If emails appear to send successfully but are not received:

  • Check the recipient's spam or junk folder.

  • Review any mail filtering or quarantine policies.

  • Ask your IT team to review the email server logs.

Connection Errors

If Cloud Assess cannot connect to the mail server:

  • Verify that the SMTP server address is correct.

  • Confirm that the port number matches your email provider's requirements.

  • Ensure that firewall rules allow outbound connections to the specified SMTP server and port.
