Re: [QF-Test] POP3 SSL Handshake Exception with Jython

Hello Charlie,

thanks a lot for the update, it's great to hear you found a solution.

The all trusting provider implemented in Java might conflict with
secure RMI used for the daemon and possibly other code that requires
SSL, like the HTTP request node. The Jython solution looks fine.
Perhaps we can incorporate it into the qfs.qft standard library. If
you could send me your current version I'd appreciate it but it's not
essential.

Best regards,
    Greg

> I am using the deleteMessages procedure found in qfs.qft to delete messages on an exchange server.  This procedure worked previously with an exchange 2003 server that did not require SSL.  The server has been upgraded to 2010 and requires SSL now.  I modified the procedure to use the POP3_SSL package instead of POP3.  I however cannot connect through QFTest, I get the following error:
