striping sender information with execption of from field

Dear ......,

I'm using procmailrc on a virtual server and don't want people to see from
what server the mails are forwarded.

Is there an easy way to do this?

example:
mail send from marcel(_at_)tip(_dot_)nl to hermans(_at_)tilburg(_dot_)com
the mail is forwarded to michelle(_at_)valkenswaard(_dot_)com but will show all
information of the hermans(_at_)tilburg(_dot_)com server.... (where procmailrc 
is)
I'd like the mail to only show from marcel(_at_)tip(_dot_)nl to 
michelle(_at_)valkenswaard(_dot_)com

Thank you :)

with kind regards,

Marcel Hermans
