Your SPF record doesn't authorize Google to send mail. Even though FrostSender connects via Gmail, your SPF check will fail — recipients will treat your mail as suspicious.

Where your inbound mail is delivered
mxa-00553301.gslb.pphosted.com, mxb-00553301.gslb.pphosted.com
Your MX records point to mail servers other than Google's. Because FrostSender connects through Gmail OAuth, Gmail and other inbox providers will treat mail you send as spoofing — outgoing delivery will fail.
