Correctness of SPF for 3 addresses?

Question

Domain Name System

Tell me who can, I'm not very selenium, the task is this
1 sender domain domain1.ru / SPF record is configured on it and mail is sent via the wp my mail plugin from [email protected]
---
specified as:
2 address for replying to the letter [email protected] mail is substituted
3 bounce address [email protected]
Such an architecture forced by the host / migration is not possible yet anyway.
----
Back in https://www.mail-tester.com/ , when checking, it always gives me scribbling that I do not understand.
It seems like DKIM passed the test, it costs -2, for example, and writes - the value will increase if you CONFIRM the dkim record, the whole Internet rummaged how to confirm it, I don’t understand what.
// ptr on the host is not possible. :(
Help explain to a newbie. Maybe I'll be useful in the future. Thanks in advance to everyone.
With respect to you and your business, Matveev E.

Answer 1

The setting is not clear to me.
Off topic at first. I’m silent about your knowledge of the Russian language, but your [email protected] will be seen by many more people, so correct it on sUpport. Don't think, don't claim, it's up to you. Just a note so that they don't laugh at you later.
On business.
Each domain needs a separate ptr and spf entry. And DKIM too. How to set up, I can help.

Answer 2

And the question is why is this possible - the client writes to me in response to my letter - and it ends up in SPAM, is it also because of the records?
