What software do you run on port 25? In particular, DMARC reporting hinges on
the results of email authentication, that is DKIM and SPF evaluation on
received messages. That is usually performed by a mail filter combined with
the MTA software.
Which third-party services may I refer to that can handle the DMARC reporting
task for me? I know Google, Microsoft, and some other providers do this but
could not find any appropriate link on how to use these providers to
send reports on my behalf.
I don't know on any third party doing that job. Indeed, for them to send DMARC
reports, you'd need to provide them with your authentication results per
sending IP number, which is the data contained in DMARC reports.
Note that I want to enable DMARC reporting for inbound emails (want to send
DMARC reports to those who want them) via a third-party provider. For outbound
emails, I have added a subdomain that can receive reports, so, no worries there.
I also don't want to set up my own reporting software, that just adds up to the
hassle.
You probably have to delegate email authentication to a third party as well.
The party that filters your incoming messages —verifying DKIM signatures and
SPF values before forwarding to your server— is the one that can do DMARC
reporting for you.
Best
Ale
