Bounce mail with gmail on vte 4.4.1

Hi anyone,
I started using the newsletter module and I setted up the ProcessBouces.config.php with the email This email address is being protected from spambots. You need JavaScript enabled to view it..
The mail server for mydomain.com is a Goggle Apps for business.
In vte the smtp is configured to use the address This email address is being protected from spambots. You need JavaScript enabled to view it..
I saw that the error messages, like mailbox full etc..., return back on This email address is being protected from spambots. You need JavaScript enabled to view it. instead of This email address is being protected from spambots. You need JavaScript enabled to view it..

There is some special configuration to do with Google Apps (gmail.com). Here below you can find the message header of a message delivered to a my personal email on alice.it. You can see that the Return-Path, thath sould be This email address is being protected from spambots. You need JavaScript enabled to view it., is This email address is being protected from spambots. You need JavaScript enabled to view it.. Also I read in google search that the Errors-To header is not used from all the smtp server.

Thank you

cp
