Based on this link how to set up SPF and answer in closed topic here My dns record looks like this
v=spf1 a mx ip4:xxx.xxx.xx.xx -all include:_spf.google.com ~all
but google throws an error
spf=softfail (google.com: domain of transitioning admin@smmmoney.com does not designate xx.xx.xxx.xxx as permitted sender) smtp.mailfrom=admin@smmmoney.com;
Is my record valid? Why doesn't it pass Gmail's filter? I am using PLESK 17.8.11 on VPS server.
EDIT 2
My domain is smmmoney.com. Changed as advised but still not working. Dns shows record is up to date.
