[mailop] How to delegate DMARC reporting to third-party providers for inbound mails

[Muyeed Ali via mailop]

Hi everyone,
I have a self-managed SMTP server and want to make my domain DMARC
compliant. I have added a DMARC record to my domain and also want to be
able to send DMARC reports if a sending entity asks for one.

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.

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.

Thanks.

Best regards,
Muyeed

Anyway, using SPF on shared environment is something, what negates SPF 
purpose at all, as anyone from that shared provider can succesfuly pass 
SPF for any other domain in it (sharing the same TXT records).  Thus in 
these shared services is SPF mostly cosmetic or part of PR/marketing 
only. Whole result then depends only on that, if particular provider 
checks spoofing from own customers, which is a) not published and b) 
moves trust to smewhere else.


I don't agree with SPF being mostly cosmetic on a shared hosting 
environment.  Yes, other people on the same host can send messages 
without authorization while still passing SFP checks.  However, others, 
not in said shared hosting environment /can't/ send messages while still 
passing SFP checks.  The difference is in the scope of who can pass SFP 
checks, the /just/ the shared hosting environment verses the entire 
Internet.


I believe there is some value in SPF even in a shared hosting 
environment.  It's just less value than in a dedicated hosting environment.

Huh, wonder if that got caught in an existing spam rule, an ML inferred
rule, or just that quickly pissed off users to mark it as spam?

Happy Cyber Monday, ya'll.
Not sure who needs to hear this, but sender with high domain / IP rep added a 
checkmark emoji ✅ to their From name and Gmail blocked it entirely as 
unsolicited mail... on Black Friday. Gmail is 70% of their customer list... I 
mean, I get it, probably not the wisest move, but...
Hope this helps someone someday.

[mailop] Proofpoint blocking issue

[Ewald Kessler | Tripolis via mailop]

Hello,

End of last week we’ve had DNS problems, resulting in IP blocking issues at 
Proofpoint. We reached out to Proofpoint (the delisting form) and via email to 
postmaster. Unfortunately, without any result so far.

Anybody able to share suggestions on how to get in contact with Proofpoint 
postmaster?

Thanks,
Ewald
