Apple Mail can send through supported Gmail or Mailgun SMTP configurations.

The Claim

Mailgun configured with a Gmail account does not permit third-party email clients, including Apple Mail, to send email through that configuration.

Verified by Lenz ·

The Short Version

The evidence does not support a blanket prohibition on sending from Apple Mail or other third-party clients. Gmail permits supported clients using OAuth, and Apple Mail can also use Mailgun’s SMTP service with appropriate credentials. Legacy password authentication and restrictions on presenting Gmail addresses through external services may block particular setups, but they do not establish a general ban.

Caveats

  • Gmail’s retirement of legacy password authentication does not prohibit third-party clients that support OAuth.
  • Gmail anti-spoofing and sender-identity rules may prevent some Gmail-address configurations even when SMTP access works.
  • Several Mailgun-specific examples come from dated or nonauthoritative community and vendor sources.
