Email setup on Ubuntu "Auth.form.error.email.invalid"

Good day to all,
I’m currently setting up a strapi installation on an Ubuntu 20.04 LTS server.
However I have come across a bit of a pickle regarding the emails.
Does anyone have advice on how to setup the email to work when resetting a password or newly registered users.
I have setup sendmail on the server and on the strapi api, yet I get the pretty troublesome error:

"Auth.form.error.email.invalid"

Any advice on how to get this matter solved in as little time possible?
Greetings

If you are using the default provider, make sure you install the sendmail package: sudo apt install sendmail

Did that,
Still same error

"statusCode": 400,
     "error": "Bad Request",
     "message": [
         {
             "messages": [
                 {
                     "id": "Auth.form.error.email.format",
                     "message": "Please provide valid email address."
                 }
             ]
         }
     ],

Did you configure sendmail ? As far as I know, you need to configure it before using it. In addition, I heard others saying it is easier to use a third-party service such as sendgrid, mailgun, etc. than setting up sendmail.

This issue probably is able to help you.

Hope these references helps too :

@SorinGFS I believe you had some interaction on properly configured sendmail right?

Test mail seems to be working using sendmail,
But no such luck on:
forgot-password
or the confirm account trigger for:
/auth/local/register
(only these 2 have I tested)

I didn’t say anything on this topic, did you ask me? :slightly_smiling_face:

Ah it was probably someone else, sorry got confused
