Subject:        Is there a way to specify a queue when sending e-mail?

I have defined several queues on my OTRS 2.0.4 server.
For DNS requests, WEB services, new install.
Users are normally supposed to handle only the requests they are responsible for, DNS,WEB,install,etc.
I accept requests send by e-mail.
And I would like if there is a way to automatically direct the requests, coming by e-mail, to the correct queue?

Many thanks in advances
Andre
