Additional outgoing mail servers can be configured

In email clients and servers, additional outgoing mail servers can be configured to allow users to send emails through different mail servers or services. This is often referred to as a "relay" or "smart host" configuration.

Here are some scenarios where additional outgoing mail servers might be configured:

  1. Relaying through a third-party mail service: A company might configure their email client to send emails through a third-party mail service, such as SendGrid or Mailgun, to take advantage of their email delivery infrastructure and analytics.
  2. Using a different mail server for specific domains: An organization might have multiple domains and configure different outgoing mail servers for each domain. For example, they might use one mail server for their company.com domain and another for their subsidiary.com domain.
  3. Sending emails through a specific mail server for a specific purpose: A user might configure their email client to send emails through a specific mail server for a specific purpose, such as sending newsletters or promotional emails through a dedicated mail server.
  4. Using a mail server with specific features or settings: A user might configure their email client to use a specific mail server that offers features or settings that are not available on their default mail server, such as better spam filtering or more advanced email tracking.

To configure additional outgoing mail servers, users typically need to:

  1. Access their email client's settings or preferences.
  2. Look for the "Outgoing Mail Server" or "SMTP" settings.
  3. Enter the hostname or IP address of the additional mail server.
  4. Enter the port number used by the additional mail server (usually 25, 587, or 2525).
  5. Enter any required authentication credentials, such as a username and password.

By configuring additional outgoing mail servers, users can take advantage of the features and benefits offered by different mail servers and services, and improve the reliability and performance of their email communications.
