I added spf record for my domail klimazon.com and 

https://mxtoolbox.com/ returns correct record  v=spf1 include:zoho.com ~all

BUT: at control panel  https://mail.zoho.eu/cpanel/index.do#domains still а yellow mark AND letters are sent WITHOUT digital sirnature. GMAIL shows a question mark near subject and says that the letter may be not from my domain klimazon.com and maybe SPAM  (screenshot  https://s.mail.ru/6f1i/B7tSWWUJr )

Please help.
