Ever wondered how your email actually reaches its destination?
In this episode of Technically U, we pull back the curtain on SMTP (Simple Mail Transfer Protocol) — the invisible engine behind every “Send” button you click.
We break down how SMTP works, from commands like HELO, MAIL FROM, and RCPT TO to real-world routing, security frameworks like SPF, DKIM, and DMARC, and how cloud platforms like Amazon SES and SendGrid modernize email delivery.
🔒 We also cover SMTP security flaws, ports (25, 587, 465), STARTTLS encryption, and the future of email infrastructure.
📌 Perfect for IT pros, developers, cybersecurity analysts, and anyone who wants to truly understand the tech behind their inbox
