看来是不支援 MIME , 因为有些 cc mail 之类的 mail system
不支援 MIME , 故後学通常只用 UUENCODE , 我也来贴一下
MIME 试试看.

末学将整封信存为 untitled.uue (如 attach file)再用 winzip6.2 来解, 得到
三个档
0001.txt : 内容是 email header
0002.txt: 内容是此信的内容
MIME.zip : 应是 heaven 的 attach file, 但用 winzip 6.2 来解时出现,

Message WZ40

The Zip cannot be opened.  If this Zip is part of a backup set, please
insert the last disk of the backup set and try again.  Both PKUNZIP and
WinZip need the last disk of the backup set to read the
end-of-central-folder record.  You may subsequently be prompted to
insert other disks from the backup set.  This is normal PKUNZIP
operation and is not specific to WinZip.
If this Zip is not part of a backup set it may be corrupted.  You can
try running the PKZIPFIX program distributed with PKZIP to "fix" the
archive.

文明兄真用功, 後学看到也是乱码, 就心满意足了, 就怪罪给 MIME 就好了.
见兄提起, 後学也试了一下, 果然用 WINZIP 无法直接还原.

後来我又用 WINCODE 2.7.3 去解, 就顺利解开了!

我是用 Microsoft Internet Mail 发的信.

我用 winzip 解出来的 mime.zip 只有 120  bytes.
用 wincode 解出来的却有 401 bytes.
而原稿就是 huiqun 所附的 a-h.zip 的某一个,
大小也是  120 而已. 不过 winzip 解出的 mime.zip 和原来的已有不同了.
不知为什麽? 也不知为何 wincode 放大成 401 byte?
不过, 手中多留几套编/解码程式, 以备不时之需也是重要的 :)
