Setting Up

Airmail

Add the gateway as an SMTP account in Airmail.

  1. Open Airmail → Preferences → Accounts, and select the account you want to send protected attachments from.
  2. Go to the Advanced (or Server Settings) tab for that account.
  3. Under Outgoing Mail Server, enter the gateway's inbound server settings — server address and port.
  4. Set the security type to match the port (SSL for 465, STARTTLS for 587), and enter your account email as the username.
  5. Save and send a test message to confirm it routes through the gateway.
Airmail's exact menu layout differs a little between the macOS and iOS versions — this covers the macOS app; see [iOS Mail](/setting-up/ios-mail) if you're looking for the built-in Apple Mail app on iPhone/iPad instead of Airmail's own mobile app.
