1.      So I'm creating contacts and I'm granting them Portal Access.

2.      Then users receives an invitation email generated with template "Portal: new user". He can then set his password following and URL inside this email.

3.      After he successfully sets his password he immediately receives an confirmation email from template "Auth Signup: Odoo Account Created".

4.      But also second email is scheduled and it is sent when cron job fires. So user receives the same email twice in the span of few minutes.

Why is that? How to prevent Odoo from sending that second email? I'm not able to find where it is generated.

The first email seems to be created in the "/web/signup" controller (it has "force_send=True" parameter so I guess it tells Odoo to send it immediately).

I'm using Odoo8.
