This is not possible natively. Exchange 2003 does not support attachment blocking on email. This feature has only been introduced in Exchange 2007. You must therefore either upgrade, or rely on third-party software.

Also, I would be very wary of attempting to block within ZIP files. Most software will only allow you to block all ZIP files, rather than the contents of compressed archives.

The methods described above only work for users VIEWING their email in either Outlook or OWA. It does not prevent users from transmitting attachments around the network for delivery on other devices, such as a PDA, or sending such attachments externally.

These approaches also do not allow you to scan inside compressed archives - you MUST block all .ZIP archives if you wish to prevent users sending compressed executables.
