[cleanerrr]

Hi
I finiched update to Contao 4.6 and everything is OK. Only, I have problem with sending members registration, and also contact form.
I see many answers about this problem, but for me error is still here:

I found this solution, but I am not sure what I need change:

Somebody tried this solution ?

The "easiest" solution would be to configure an SMTP server in your parameters.yml

The "easiest" solution would be to configure an SMTP server in your parameters.yml

This is my parameters.yml:

# This file has been auto-generated during installation
parameters:
    database_host: localhost
    database_port: 3306
    database_user: 00000000
    database_password: xxxxxxxxxxxxx
    database_name: xxxxxxxxxxx
    secret: xxxxxxxxxxx

You mean I have to add this:

mailer_transport: smtp 
    mailer_host: myMailserver 
    mailer_user: administrator@mydomain.com
    mailer_password: *********** 
    mailer_port: 
    mailer_encryption:

What did you set for mailer_host?

[Spooky]

Post your complete parameters.yml but without any SMTP and database username and passwords (!).
