Hello!

I'm trying to install a Sympa instance on my Debian 8 container.
I installed it with apt, and then configured it to use my MariaDB server (instead of the default MySQL installation) and NGINX (instead of Apache2).
Then I had configured Postfix as described here, and here.

So now I'm able to connect in the Web Interface. I created a Mailing List, I invited myself on the list, I received the "Welcome to list listname" message.
But when I try to send a message to the list, I have an error message:
I really don't understand this error, because it seems that Postfix and Sympa are working well together (I can send emails, I can receive emails), but just Sympa don't recognise it as a mailing list..

Does someone have an idea of what can I do to solve that?

Thanks!
Tonio-

Tonio, you've marked this thread as "Solved".

What was your solution?

Hum, it's not related to Sympa.

I had two instances of Sympa running (one in the VM I did my tests, and one in my prod env). Postfix was talking to the one in prod, and the Web interface was talking to the one in test.
So when I created a list, the env test was able to send me the email to confirm, but when I answer the prod env didn't know this list.

Just my bad

No "bad" at all. You live and learn. Glad you resolved it!
