Hi, I am new to bonita and attempting to set up some simple test processes.  I am having difficulty configuring the SMTP connector to send out a test mail. I have connectivity to the mail server and have opened all necessary ports from my machine and on the server.  i can ping and telnet to the exchange server as well as send a mail through telnet. I have set up the connector using the connector Email (SMTP) (1.0.0) -- Send an email using SMTP (RFC 5321) but when I try to sent the test I get the error: java.lang.reflect.InvocationTargetException org.bonitasoft.engine.bpm.connector.ConnectorExecutionException: org.bonitasoft.engine.core.connector.exception.SConnectorException: org.bonitasoft.engine.connector.exception.SConnectorException: java.util.concurrent.ExecutionException: org.bonitasoft.engine.connector.exception.SConnectorException: org.bonitasoft.engine.connector.ConnectorException: Could not connect to SMTP host: 192.168.16.38, port: 25 Its an exchange 2007 test environment and I am running the latest Bonita package on standard windows 8.1.  Have also disabled the local firewall but it made no difference. Any help would be appreciated.   ---

Hi Gary did you find out what the problem was? I am having the same error with Bonita 6.1.1 when attempting to use an SMTP server which works fine when using telnet to the same server and port as I have defined in the connector. ---

In fact I have found the answer for my case myself. By default the SSL [] checkbox is ticked under Security on the Connection Information configuration page. When I unticked the checkbox this SMTP conector worked perfectly.
