If you are trying to configure your wordpress installation to send email from your gmail account:
- Install the ‘Configure SMTP’ plugin, and check the ‘Send e-mail via GMail?’ box.
- Send a test email to make sure everything is working.
- You just need to open port 465 on your firewall. You might need to ask your hosting provider / system administrator to do this for you.
- If it still doesn’t work, you might need to double-check your gmail password..
