Yes. The problem is that DBF.EXE is self-extracring rar archive which includes
few files with the same names as other files in .zip archive. It is easy to
reproduce. Make 3 text files and name them eg file1, file2, file3. Make .rar
archive eg archive.rar and pack file2 and file3. Then, make .zip archive that
includes file1, file2, file3 and archive.rar. When you send that .zip archive
through MailScanner the problem will occure.

If it is safe to overwrite already unpacked files (are they already scanned?)
then -y can be a solution.
