It seams the connection to the exchange server is not possible.

Please check if you can connect to the SMTP port from the machine where Kunagi is running. You could try this with telnet correo.obremo.es 25. If this doesn't work, you have to configure your firewall or exchange server to allow such connections.

If the connection works pleasy try to find more info why the connection from Kunagi does not work. What ist the log text after nested exception is:?

Hello,

Sorry, we only use SSL for SMTP. I've changed the configuration in KUNAGI
SMTP server correo.obremo.es
SMTP port - 443 +
SMTP TLS yes
SMTP user herminio.martin@obremo.es
SMTP password xxxxxxx
Sender email informatica@obremo.es
Administrator email informatica@obremo.es

and the error ; (the user is herminio.martin@obremo.es but KUNAGI add @correo.obremo.es)

THANKS IN ADVANCE

The error message says, that your SMTP server has reset (closed) the connection. You will have to look into your SMTP server logs why this happened. Sorry, but as Linux user I have no idea how Exchange works and where it stores information about failed connections.

Hi,
Did you found solution for above problem ?

Hi Rohit,

as stated previously, this looks like a problem with your Exchange server rather than Kunagi. In any case, from the stack trace shown here, it is not possible to find out why the server closed the connection. You would have to see in your SMTP server logs what happened.

Kind regards
Artjom
