What should be done if the outgoing SMTP server is not usable on certain Wi-Fi or cellular networks?

When the outgoing SMTP server is not usable on specific Wi-Fi or cellular networks, adding an alternate outgoing server is a practical solution. This approach helps ensure email can still be sent when the primary SMTP server encounters issues, such as network restrictions or misconfigurations that may block access to that specific server.

In many cases, certain networks—especially public or workplace ones—might have security measures that prevent the use of certain SMTP servers due to their configurations. By having an alternate SMTP server added to the email client settings, users can switch to a different server that might be more accessible, enhancing their ability to send emails regardless of the network they are connected to.

Furthermore, the other options do not directly address the issue at hand as effectively. Restarting the computer may resolve some temporary glitches but is unlikely to solve specific network-related SMTP issues. Changing the email password is only necessary if there's a security concern or a miscommunication with the server regarding authentication, which may not pertain to network usability. Disabling the firewall could expose the device to security risks and is typically not a recommended first step, especially if the issue specifically pertains to the SMTP server access on certain networks. Adding an alternate outgoing server provides a specific workaround that keeps security intact while resolving the
