Yandex 360 mail address cannot sent mail to my Mailcow server.
No any “Undelivered Mail Returned to Sender” reply.
I checked what using IP address by Yandex mail, i find 220.127.116.11.
Look like reported as Abuse 2 times in abuseipdb.com and blacklisted by some services.
How i can whitelist this IP for bypassing Mailcow blacklistes and Rspamd?
