Procmail rule

[Swapana Ghosh]

Hi 

        Though it is really a silly qs but as i have
not written the procmail rules yet - so asking because
i want to patch it to the production server.

Some mails are coming to our mail inbox like 
             [ user at www.domain.org ]

when it is coming to inbox it is showing as full sting
as  above . But i want to change it as 

              user at domain.org

So what is the rule i will write in the /etc/procmail
file.... 
Hints/any site relted to my requirement will be
helpful.

Thanks
-Swapna
