I have been trying to learn about phishing emails. I have read up quite a bit on it. I setup a domain somthing.tk (free domain), hosted a website on a VPS (Digital Ocean). Set up my own mail transfer agent (Postfix).
Now I have set up:
All pass in GMail when I send the mail, but still the mails send by me are flagged as spam by GMail spam filter. What am I doing wrong?
Also I am using GNUMail to send emails via this command:
echo "anything" | mail -s "subject" firstname.lastname@example.org
