Analysis: What happened with Yahoo! and DMARC?

Or: Why is my mailing list broken?

It’s all over the media, the DMARC-discuss mailing list is full of postings: Yahoo! has switched to a DMARC „p=reject“ policy. This broke many mailing lists and now people are crying out in horror.

DMARC is a protocol to describe policies to mitigate phishing via e-mail. Put in a nutshell it basically enforces that a message came directly from the domain shown in the From-header or was at least signed by that domain. For details and precise descriptions check out dmarc.org. And yes, I think it’s a great idea.

So, what did Yahoo! do precisely?

To determine this I wrote a small script querying all DMARC policies of all „yahoo“ subdomains below all effective top level domains.

WARNING: Only run this script if you exactly know what you are doing. It is going to make about 7.000 DNS requests in a relatively short time frame, thus killing your internet connection, depending on the abuse policy of your ISP.

Here is the summary:
./checkdmarc yahoo
Running query, this may take a while ...
SERVFAIL: 44
connection timed out; no servers could be reached: 27
has no TXT record: 69
NXDOMAIN: 6011
is an alias for: 95
p=none: 50
p=quarantine: 1
p=reject: 279

Your experience may vary. Also the script might not catch all possible DNS responses. But you get the picture:

Yahoo! activated p=reject on at least 279 domains, p=quarantine on one (yahoo.ne.jp) and 50 domains are running a p=none policy.

The 50 domains seem to belong to European countries and domains that refer to commercial usage mainly. This might be explained by the (sad) fact, that DMARC and its base technologies (SPF and DKIM) are widely used everywhere except in Europe.
