Hi Tou
Thanks for your response
As stated above, if you put a gmail id in Joomla > Config > Server, it won't send emails there.
That is because PHP mailer and SMTP won't send emails to recipients outside the domain of the website - this is configured in the DNS to prevent Spam and as you can see, my domain use SSL encryption.
So the only way to test emails in Joomla > Config is to use a proper domain for the recipient.
Please check the code in Finion contact form as I'm sure the problem could be in your component.
For example, I'm using your Stellar template with same server configuration, and the contact form works fine.
Is the contact form using the same code as Finion?
Have you tried sending emails with Finion from a SSL website?
What Email configuration and DNS records are you using?
