The external SMTP server sends to gmail and yahoo, hotmail or spam or does not reach at all, how to fix it?

Question

Yahoo

The server is working on a notification for those who subscribed to the webinar. We noticed that yandex mail and rambler receive notifications stably. But gmail, yahoo and hotmail - stably in spam or do not come at all.
DKIM and SPF are worth it. In black it was checked - norms, something with the settings
What needs to be corrected and where? I've been poking around in the ISP panel for three days without getting
out, so I sent the title of the letter to myself!

dkim=fail

you have dkim configured incorrectly

something incomprehensible, I think you need to fill in this section as follows:
"the k = rsa; p = MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCb / IpGdZp2CRXrX4MMnXmWDavs9VFtuE6bY6UJO87Xc3qToa61EPiIdt4LUj1JLJvd2g3laCCO7JLvv0fBqd20eDlUV6x5SJPasfPPRUGWdPo3QECncuz6Q + 75IV4FKIhVvuyTAvFSM8U5F4aqn0qvyAYGXkCd8Fc9MkcrQDBRqwIDAQAB"
