Definitions

  1. Simple Mail Transfer Protocol — the standard protocol for sending email across the internet. SMTP handles outbound delivery between mail servers on port 25 (or 587 for submission), while IMAP/POP3 handle retrieval.

    In plain English: The protocol that actually delivers your emails from one mail server to another across the internet.

    Example: "Configure your SMTP relay credentials in the .env file so the app can send transactional emails."
