Email sending not working on setup (PHP/WordPress)
I have WordPress installed on a Droplet with WP SMTP plugin(with Gmail setup configuration). It works when I send a test email via plugin page inside WordPress admin panel. Follow to that, I installed postfix to deliver emails. I have WordPress Contact Form (contact form 7) plugin installed which triggers email sending.
But, when I run this command, and check my inbox, I don’t receive any email.
echo "Test Email message body" | mail -s "Email test subject" <my-email-address>@gmail.com
When I checked my log file (
tail -20 /var/log/mail.log), following is what I see there.
