Possibly, but if Amazon isn't doing enough to secure SES against abuse by spammers(1), it's not unfair for entities intended to guard against spam to treat it as a spam source. This is one of the risks of letting third-parties run software on one's systems.

(1) keeping in mind that the definitions of "spam" can be quite subjective

Amazon SES definitely does have a spam problem, and the issue is that they don't bother doing anything about abuse reports. I've reported a spammer (who scraped our email address) to them, but the spams kept coming. Other people have reported the same thing.

If you're running a bulk mailing server you simply must respond to abuse reports, otherwise your service will get blacklisted and be essentially useless. Other providers such as mailchimp are much more proactive about getting rid of spammers.
