Hi. I have a Mendix server running on a virtual machine with windows XP installed. When I start the console everything seems to be ok but I am not able to send any e-mail from this application. In testing and development environments everything works fine. My email host is 'smtp.gmail.com' and I'm using the port 465. I also have configured that it must use SSL (true). The error that I receive is concerned to the host server. What could be the reason for this? UPDATE I have a microflow that calls the microflow 'SendEmailMessage' from the AdvMail Module. The microflow is the following: The error(message( that I get is the one from this microflow: The configuration of the console is the following: The application works perfectly well when I'm running on the Modeler but here in production it doesn't work. I don't see any mistake and as I already posted, I can send e-mails from Thunderbird with the same configuration. SECOND UPDATE After removing the custom handler error, I just get a simple error message on the screen. Looking in the log file I found this: 2011-09-27 16:13:25.618 ERROR - Connector: An error has occurred while handling the request.

Modeler but it still doesn't work in Production. THIRD UPDATE I have also runned the application from the App Store called 'Public Profile' (that doesn't exist anymore or I couldn't find it) in a production environment and I got the same error: the smtp was unknown. I'm using the port 8081 as HTTP port, 8090 for the Server admin port, 1525 for Oracle database and the 465 for smtp (I already tried 587 and 25) but nothing seems to work in my application and the application from the app store.
