Sending message from CB does not work

May I remind that emails are correctly sent by Joomla mass mailing.
Moreover, I've just test emailing from my site's Kunena forum, it DOES WORK

Seams there is no issue with Joomla->SMTP

The problem seams to be located on CB ie CB registration mailing workflow and Mass mailing DO NOT WORK.

May I add that, before activating the registration with CB, I used the Chronoforms plugin to do the registration process. After adding CB, I have desinstaled Chronoforms.

Is it safe to desinstall and reinstal CB, I mean, will I keep the CB Setup that I have already done?

From the URL I already pasted you:

Mailer: SMTP Server
SMTP Authentication: Yes
SMTP Security: SSL
SMTP Port: 465
SMTP Username: Your Google Username
SMTP Password: Your Google Password
SMTP Host: smtp.gmail.com

Note you may need to append the port to the host as follows.

SMTP Host: smtp.gmail.com:465

Hi Nick,
Be sure I do appreciate your help.
But I don't understand the purpose of this setting (sorry if the point seams obvious to you).
My SMTP settings do work with Joomla mass mailing and Kunena Forum.
Why should I try another SMTP server?
Best regards

As Kyle proposed in the thread I gave you.

Please try and configure your SMTP settings (in Joomla) as:

SMTP Host: auth.smtp.1and1.fr:587

and see if this works.

As far as Joomla is working - are you sure it is using SMTP and not falling back to PHP mailing?

I try the configuration of the SMTP host : auth.smtp.1and1.fr:587
(sorry, I didnot understand that in your previous post you just meant that I should add the port at the end of the SMTP host)
As a result, Joomla mass mailing is still working,
but the CB one is still not working :S
