Hope it helps

Axel and Nils, thank you so much. 

It looks like I have to dig it much, maybe I should  ask my email provider to help me out

I have done this before and it's a matter of put the proper relay or smtp server and no username and password, leave it empty and save the Outgoing Mail Server.

After that just make sure that the company email and your current user(admin) email it's allowed to send emails using that smtp server or relay and you should be good

Hey Jilong,

you need to have at least the authentification by user name, which is actually the email adress you are using. 

So you ned to set up the username (emailadress) and the password. It depends a bit on your Email-provider if you are able to use it (Microsoft email addresses e.g. won´t be possible this way.)

SSL as authentification just refers to the case, when you want to have the secure sockets layer during authentification.

So what you need at least:

- username (email adress)
- password
- Server adress given by the email provider

TLS/SSL again depends on the Requirements of the provider. So make sure to choose the proper one and use the right ports.

and don´t forget to set the domain in the general settings.
