Issue using form with email plugin

Hi there!

I’m trying to build a contact form and though i tried to follow docs, it seems I’m still missing something.
On my server I have postfix installed with all the needed certificates to send emails.
If i run this command sudo bin/plugin email test-email -t <my-email> I receive it.
But if I fill the grav form and submit, it seems the service doesn’t even get called.

This is my email plugin configuration:

enabled: true
from: <my-domain>
to: <my-email>
mailer:
  engine: smtp
  smtp:
server: <my-server-ip>
    port: 25
    encryption: none
    user: null
    password: null
  sendmail:
    bin: "/usr/sbin/sendmail -bs"
content_type: text/html
debug: true
cc: null
bcc: null
reply_to: null
body: null

and this is my contact form frontmatter

@bebiuz, You should not create a custom template. The Form plugin will take care of it. The email process action defined in the form definition will redirect data from the form to the Email plugin.
