DKIM is fine at the organizational domain. I do think it's related to
the introduction of new identities, and with time the filters will learn
the reputation of the new identities.

But this may be related to the drop in reputation of Amazon SES IP Space. Do
they offer a dedicated outgoing IP Address that you can try? It also helps
reduce any chance of forgeries.. Eg, smaller SPF footprint, that could have
poisoned your reputation.
DKIM should help as well or even better.
_domainkey.newsletter.syniumsoftware.com produces NXDOMAIN which means domain
keys don't exist.
Hi,
Thanks for your response. DKIM is set up according to the AWS SES documentation.
There are three DKIM records for AWS SES present in the DNS record of
syniumsoftware.com <http://syniumsoftware.com/>:
5tciaamivsdm3um6jda5iawx6dkzl4vv._domainkey.syniumsoftware.com
<http://domainkey.syniumsoftware.com/> =
5tciaamivsdm3um6jda5iawx6dkzl4vv.dkim.amazonses.com

<http://ypcsbtqri7hjsoyf55sdheq4elds3ojh.dkim.amazonses.com/>
These SEEM to pass validation according to the DMARC reports we’ve received.
Now my question: We’re sending using the Email address newslet...@syniumsoftware.com
<mailto:newslet...@syniumsoftware.com>. The return-path/MAIL-FROM domain is
newsletter.syniumsoftware.com <http://newsletter.syniumsoftware.com/>. I assumed that mail
servers will look for the DKIM records at syniumsoftware.com <http://syniumsoftware.com/> and NOT
newsletter.syniumsoftware.com <http://newsletter.syniumsoftware.com/> . Am I wrong?
Thanks in advance for any guidance you can provide. Highly appreciate your help.
Best,
Mendel
