how about using this solution?

/^(content-(type|disposition):.*;[[:space:]]*(file)?name[[:space:]]*=[[:space:]]*")([=\?]*([^\.|"]*)\?=)(".*)/
        REPLACE ${1}changed_filename${3}

it seems still unable to handle the case:
Content-Type: image/jpeg; name="=?utf-8?Q?=EC=8A=A4=EC=BA=9400111001.jpg?="
Content-Disposition: attachment;
filename="=?utf-8?Q?=EC=8A=A4=EC=BA=9400111001.
jpg?="

I am using microsoft outlook 2003.

Thanks.

Tom
