now winrar has a option to encrypt file names with a password, me thinks pkzip with the 64 bit compression also has that feature... how are we going to deal with this ? by stopping all the compressed mail at the email gateway ?

we do have one solutions: all the mail headers are spoofed so just stop accepting mail from spoofed host, this should solve your spam problem also

that is always being done by the all the people in this day and age, only now we seem to forget to add the compressed file format that are encrypted so that their file contects cannot be seen ?
