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://5tciaamivsdm3um6jda5iawx6dkzl4vv.dkim.amazonses.com/> owv4bewgknpmf434mvkczc5hlg3yrflg._domainkey.syniumsoftware.com <http://domainkey.syniumsoftware.com/> = owv4bewgknpmf434mvkczc5hlg3yrflg.dkim.amazonses.com <http://owv4bewgknpmf434mvkczc5hlg3yrflg.dkim.amazonses.com/> ypcsbtqri7hjsoyf55sdheq4elds3ojh._domainkey.syniumsoftware.com <http://domainkey.syniumsoftware.com/>= ypcsbtqri7hjsoyf55sdheq4elds3ojh.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 _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
