Hi Gang

Lately I came across various oddities with Amazone SES.

About a year ago, envelope sender @eu-west-1.amazonses.com was known to
send exclusively spam and thus on the personal blocklist of many of our
customers.

Now it looks like some big legitimate companies, like the major food
delivery service in Switzerland is using this domain for their order
confirmations.

Today, we got complaints that 2FA confirmations codes via email from
one of the major Swiss newspapers get blocked as those contain a link
to http://awstrack.me/ no https no path, just that link to the webserver
which is not even reachable. I don't understand why AWS is putting a
link to a nun functional website in their emails.

The domain awstrack.me was on our blocklist because of hundreds of
spamtrap hits and customer spamreports. I looked through those
complaints, they are legitimate and concern mostly phishing emails sent
via Amazon SES Services. It looks like awstrack.me was probably used as
URL shortener/obfuscator/click tracker until the beginning of
december 2024.

It also looks like AWS is using the same IP addresses and envelope
from to send email for big paying customers and what I assume are
'free' accounts used by spamer and phisher.

Is there some useful way to distinguish spam from non spam sent via
Amazon SES?
