I use Sendy with SES.
Does anyone else use (free) Postmark for DMARC monitoring, and get the weekly reports?
The Postmark report says that the email from source "amazonses.com" are 0% SPF aligned, and 100% DKIM aligned.
And there is a tip about return-path.
"amazonses.com is authorized to send on behalf of news.mydomain.com, however it looks like SPF is still failing DMARC’s alignment test. DMARC looks at the Return-Path of a message to make sure the domain there matches the domain in your From address. If the Return-Path path doesn’t match your From address, those messages will fail DMARC’s SPF alignment test. Check with this source because you may need to set up a custom Return-Path."
I see that the return-path of my emails sent via Sendy+SES are typically like this:
So it looks like VERP for bounce processing.
Is there anything I should change so that Postmark can see 100% SPF alignment? Or should we just ignore it.
if you setup the subdomain as per the instructions this should resolve... also make sure your spf has the includes for amazonses.com and any other sources of email
This is interesting - wasn't aware of this tool. Free DMARC monitoring from Postmark is where it lives, if anyone else is interested.
