Yandex 360 email authentication
Yandex’s business mail suite.
SPF record
Add Yandex 360 to your domain's SPF record with this include:
include:_spf.yandex.net
A complete record for a domain sending only through Yandex 360:
v=spf1 include:_spf.yandex.net ~all
What it costs you
4 of your 10 DNS lookups. The include: itself costs one, and Yandex 360's record chains to 3 more.
Behind it are 14 IP ranges.
Live record
This is what _spf.yandex.net published when this page was generated:
v=spf1 redirect=_spf.yandex.ru
DKIM
Enable DKIM inside Yandex 360 and publish the selector record it generates. DKIM matters more than SPF for deliverability, because a DKIM signature survives forwarding while SPF does not — see how selectors work.
DMARC
Neither SPF nor DKIM protects the address your recipients actually see until DMARC ties them
to it. Once Yandex 360 is authenticating, publish a DMARC record — start at
p=none with a reporting address and
tighten from there.
Check it worked
DNS changes take minutes to hours to propagate. Once published, run the domain through the checker — it resolves the full include chain and reports the real lookup count.
