    Emails sent from my server are being blocked as spam, I'm worried that this is due to not having the right headers. Below are the headers from a blocked email. I am using postfix to send email, my site is mywebsite.com and the name of the machine hosting my site is server123.onlinehome-server.com. I would really appreciate any help with this! Let me know if there is any other information I can give that would be helpful. Thank you.

    Is your server connected to the internet trough a dynamic IP?

    I have a static IP, and this is the only website hosted on the machine (a virtual server). My /etc/hosts file includes my machine name: server123.onlinehome-server.com, but not the website name: mywebsite.com.
