How Postfix uses SASL authentication. SMTP servers need to decide whether an SMTP client is authorized to send mail to remote destinations, or only to destinations. I loved the speaker's gift, as well! This show was a lot of fun and I certainly hope to be invited back next year! In the meantime, though, I am very excited to be.
