This is fixed in current versions of Mercury, so please upgrade. The removed attachment will be replaced with at text like this:
This section of the message has been deleted by the mail system -
it originally contained the following data:
Content type: application/zip
Content description: (None)
Filename: Test.zip
The rule may remove MIME parts you want to keep as well, so you may need to check that there is a filename (a regular expression looking for "?*" will do it).
