How to Remove SMTP Server Settings in macOS Mail

Apple's macOS Mail lets you set up several outgoing email servers. This flexibility can come in handy sometimes, but it's useful to know how to delete SMTP server settings in the event that you don't need them anymore. For example, maybe the server settings are no longer relevant to your email accounts, or maybe they're old and broken.

Regardless of the reason, you can remove SMTP settings in macOS Mail using these steps.

  1. Open the Mail app and select Preferences under the Mail menu.
