Changing sender name notification mails

[plucky]

Dear,

I'm reseller at DA.
All of the notification mails (like bandwidth messages) are send with the following sender- and recipient-address: [email protected]

We have some own IP with reverse dns so user can't see where we host our sites with a trace.
What I want is to change the sender- en recipient-address in: [email protected] so our customers can't (easily) see where we host.

How and where can I change it?

Thanks in advance!
Plucky

PS. I hope you understand my question, I'll try to speak English but it isn't that good.
