DMARC is not something I'm well-versed in, but was trying to do what tests I 
could. Would be interesting to see what would happen if someone deliberately 
tried to send from a non-SPF valid IP.

Normally, it just sorta works, but I've never actually seen the traffic it 
generates, or seen the software that is supposed to send it, so I'm unsure 
exactly how to poke it with a stick... :(

Aloha,
Michael.

My bad, I should have included this issue has spanned well over multiple days 
so the 24 hours rule wasn't a cause.

I queued a few different customers I know with valid DMARC records and I'm 
seeing the  “\” in front of the “;”’s.

I will however dig into the greylisting. As always, thank you all for looking 
into this and helping out!

ha, no worries. That's fair enough. Here's the customers DMARC record.

The domain

?Again we know that this does not currently have the ?"pct=100" tag, but with 
or without the results have been the same.

Not including that is about on par with the legendary complaints of:

“ It Doesn’t Work.
“ I Can’t Print.
Etc,

At some point, we’re going to ask you for it anyway, so best to just provide it 
at the start.

Subject: [mailop] DMARC record in p=none not receiving aggregate reports to RUA

We have a customer who's setup a DMARC record with the correct TXT record; 
v=DMARC1; p=none; pct=100; 
rua=mailto:dmarc@<mailto:dmarc@>"customerspostmaster" after waiting the 24 hour 
period we still did not receive any aggregate reports to the mailbox. After 
some searching we advised the customer to try and take out "PCT" as that could 
possibly have been triggering something to not work correctly (shot in the dark 
try).

Then after that attempt and no result I did some more research and found that 
in some instances reports can be huge and up to 10MB and denied by their 
internal servers. We then advised the customer to check their logs to make sure 
mail wasn't getting denied at their gateway. To no avail reports still are not 
being sent.

Has anyone else run into this problem with customers when they're trying to 
receive aggregate reporting using a rua that is in house? If so I'd love to 
hear any troubleshooting you've tried as well as possible fixes for this.

Thanks,
Dickie LaFlamme
