Hi,

For what it's worth, I would try two things.  First, what is the output of this?

7z l file.7z

Second, what if you cat the pieces together and then try to extract?  I'm
also wondering if somehow the archive got corrupted in email transit.  If
7-zip can't list it, it's probably broken and there is no point in
continuing.  I think the archive contents are stored in the header, so if
the first part is damaged, it isn't going to extract unless you use an
archive repair utility.
