amazonaws.com
Number 6 of the Top 100 · Tranco rank 8
amazonaws.com is the domain behind Amazon Web Services. Names under it, such as s3.amazonaws.com or ec2-…compute.amazonaws.com, are servers and storage that AWS customers rent, so a name under amazonaws.com tells you the host is on AWS, not who runs it. Thousands of companies, and some attackers, serve from it.

Can amazonaws.com be forged?
Partly. Forged mail goes to the spam folder, where people still find it.

- quarantine · subdomains none · reports to Your own mailbox
- Names that copy
- 17 registered lookalikes can send mail. DMARC never sees them. See them →
What we noticed
- Subdomains are at none while the domain is at quarantine. A forger uses a name under the domain, which receivers then deliver.
- The DMARC policy sends failing mail to the spam folder. A policy of reject stops it.
- The subdomain policy is none, so a subdomain is not protected.
Senders it names Amazon SES
- Amazon SES include:amazonses.com
These are the services the records name. A record can name a service no longer used, and a sender can sign without being named.
