How to correctly specify DKIM and SPF if different servers?

Question

SPF

Hello!

I have an address: moyadres.ru

Mail is opened on connect.yandex.ru

I want to send mailouts to clients via the sndpls service using the same moyadres.ru domain

DKIM records, as I understand it, there can be two.

1) sndpls writes that the entry should look like sign._domainkey.moyadres.ru txt v=DKIM1; k=rsa; p=M...
and yandex writes that the entry should look like mail._domainkey txt v=DKIM1; k=rsa; p=M...
i.e. yandex subdomain name without the moyadres.ru domain directly. This is fine?

2) How to correctly add an SPF record?
yandex writes that this entry is needed: v=spf1 redirect=_spf.yandex.net
and sndpls is like this: v=spf1 include:mxsspf.sendpulse.com +a +mx ~all
How do I correctly compose the SPF in my case?

Answer 1

1. DKIM entry should be
selector._domainkey.yourdomain
in most popular servers, when specifying a name without a child (mail._domainkey), a zone suffix is ​​added, so you need to write either
mail._domainkey
(without a dot at the end) or
mail._domainkey.moyadres.ru.
(with a dot at the end). Both entries give the same result.
2. the correct entry in this case

v=spf1 include:mxsspf.sendpulse.com include:_spf.yandex.ru +a +mx ~all

but without unnecessary need to use in SPF is not worth it, especially mx a. mxIf letters other than these two services should not go anywhere, it is better to limit yourself to

v=spf1 include:mxsspf.sendpulse.com include:_spf.yandex.ru ~all
