Adding a TXT record of openDKIM and DK-filter to the same domain

Question

Domain Name System

Hello. I'm trying to solve the problem of getting mail into spam on Google mail servers.
There are a lot of discussions on this topic, in general, they all come down to checking reverse zones, SPF records for a domain, as well as DKIM and DK signatures After

SPF and PTR were specified correctly, letters began to arrive, but ended up in spam
private and public keys were generated, a TXT record for the
._domainkey domain was added. IN TXT "v=DKIM1; k=rsa; p = MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDlVX9snIJ5BuRaIkrPfTYQwmYg9BfR0rR258xwyRoOGKCdrio1b + J5mvNOsT0AZMI / YJCjR5B3BvWWywN2J7sVHOC / Ri + 8wkMfLFXKPS6FAMb2gDrUln8H5Wh6Rayly8 + l77VaujRkiuK7NGoDA9CltYGF33LqayRoGCuuYQomjQIDAQAB »

Check DKIM confirmed its validity, but the analyzer, which I used (www.appmaildev.com/en/dkim/ ) showed that the DomainKeys entry does not exist "DomainKeys Signature validation: not available" (which is logical, since DK-filters has not been installed yet)

Tutorial about installing DK-filters "asks" to register new TXT record: _domainkey IN TXT "o=-"
Some other sites write that you need to create a separate record by duplicating the rsa key.

Tell me in what form you need to create an entry for DKIM, preferably with inserts if DKIM is already installed
And another question, the private key file is under the control rights of a user created specifically for DKIM, DK-filters cannot use it. How can I allow KD-filters to use this file so as not to create duplicates.

Thanks for any help provided.

Answer 1

I could be wrong, but DK is outdated and there is no point in messing with it. So don't worry - DKIM is enough for you.

Answer 2

You need to select a key for the DKIM entry. mykey e.g.
mykey ._domainkey. IN TXT "v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDl…
