When .rm files blocked mail files also can't be sccessed on web

When i block files of extension .rm on my linux server so that these files can’t be run,retrieved or accessesed through internet by our users.But when I access my lotus mail file through web

left pane is visible where i can see Inbox,Folder, Sent etc but in the middle pane there is a messege

that “Not Allowed by Admin” a messege which appears in our environment when a prohibited site or file is tried to be

accessed through internet. Is .rm files have something to do with my Lotus Notes web access? How can this problem be sorted out?
