Hi, I generated a dkim key using this tool https://dkimcore.org/tools/keys.html and added it as TXT record as following
v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDMvxAJ9+Pf/xshyo9qkpL+bKdtxuvNHSaQJWsnXJ7sglA4eHac7OWa8+HOS+P+NZPhpN1vdFCpee0rWfDzINf0GISRbl5iR8L6wtbfzzg1W3LiLtGVt0V0Fy19782QXUZVnNapGpKpTH8+blK0s710en3Wjtz7eMG9UFHJBHGJCwIDAQAB
and my dmarc record as following
and the record name is default._domainkey and i tried to test it using different online tools which says that teh dkim record is valid but when i sent emails to some email providers such as gmx it end in spam folder and the emails does not appear to be signed and the email header doesnt have DKIM signature which i think it may be the cause of the emails going to spam folder, so i was wondering how to fix that issue?
my domain name is "bon am ico"DOT"de
PS: Im using hostgator shared hosting and using the cpanel mail
