System Administration: Week 8: E-Mail, Part III
In this video, we look at ways to combat Spam. In the process, we learn about email headers, the Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting and Conformance (DMARC). SMTP doesn't seem quite so simple any more...
How (racist/sexist/whatever) harassment on Mastodon works:
1. Harasser replies to their target's post, with the reply set to "followers only", saying the most vile stuff you can imagine.
2. All the harasser's followers join in on the harassment, posting more vile stuff.
3. Nobody but the target and the harassment crew can see the vile stuff that was said.
4. Target is traumatized. Nobody else can see why.
5. Everybody says "I don't see it so it's not happening."
System Administration: Week 8: E-Mail, Part II
In this video, we observe the incoming mail on our MTA, look at how STARTTLS can help protect information in transit, how MTA-STS can help defeat a MitM performing a STARTTLS-stripping attack, and how DANE can be used to verify the authenticity of the mail server's certificate.

System Administration: Week 8: E-Mail, Part I
In this video, we begin our discussion of E-Mail by looking at the components of the larger mail system (the Mail User Agent, the Mail Transfer Agent, the Mail Delivery Agent, an Access Agent), observing the packets involved in a simple SMTP exchange, and track an email from one system to the other.
