Removing pieces out of the middle of a file is probably implemented in the netscape mail program by selectively writing out portions of the old file to a new file, deleting the old, and renaming the new to match the old. (The order of operations may be slightly different, there may be two file renames or something like that .. the point is, netscape probably removes that file every time mails are deleted from the folder.) One possibility is to grant only read and execute access on the directory containing the file. This will prevent file renames, deleting it, etc, while still allowing other normal file operations to succeed (modify, read, append). If netscape doesn't complain, this might work out ok. I doubt it though. :) -- Over 900 technologists agree: electronic voting isn't ready: http://verify.stanford.edu/evote.html
