Incoming emails going to the wrong queue

Hi,

I'm testing a queue "service" with an external email, like service@mycompany.com 

this is working... but... the emails are trapped by my private queue!

and the automatic creation rule in place in the service queue, with the automatic answer, is applied to the incoming emails.

So I have a case created, an automatic answer sent, all setup in the service queue... 

I dont understands why the case created finally is in my private queue.

I dont have routing rules
