Hi there, I have Vesta + Ubuntu set up on my server and have configured the necessary SPF records. When I send email from my domain name itself, it seems fine. However, for some reason, emails sent from my subdomain seems to be marked as spam by Gmail.

Attached are my headers:

What could be wrong?
