Настроил TXT запись в DNS:
@ «v=spf1 +a include:_spf.google.com -all»

В postfix стоит перенаправление с test@domain.ru на почту mymail@gmail.com
Письмо падает в спам: google.com: domain of transitioning mymail@gmail.com does not designate IPOFMYSERVER as permitted sender)

Что я делаю не так? Или надо подождать 72 часа?

dig TXT mydomain.com
и viewdns.info/dnsrecord/?domain=mydomain.com

Показывают: «v=spf1 +a include:_spf.google.com -all»
