Answer 1

Received-SPF: softfail (google.com: domain of transitioning [email protected] does not designate 123.123.123.123 as permitted sender) client-ip=123.123.123.123;
Who will set up the SPF record for you? Specify domain
in DNS .
IN TXT "v=spf1 a mx ip4:%ipaddress% ~all"

Answer 2

Because your domain is not trusted by Google. After the nth click, "Not spam" comes to my inbox :_

Answer 3

perhaps when forwarding, the sender's name does not match the forwarder's IP, which adds spam points along with spf=softfail ?

Answer 4

You need to set up a DKIM record, and then add this record to the domain records. It worked for me right away.
