Yes, because what you are basically checking for is the *existence*
of the Content-Disposition header.  Logically, if a Content-Disposition
is not present, "inline" is assumed.

You are taking advantage of a common MUA behavior where the main
message header usually does explicitly define a Content-Disposition.

But hey, if it the above works for use, who am I to argue about it.
Note, to just check for the existance of Content-Disposition, the
following will do:

    if (defined($fields->{'content-disposition'})) {
	...
    }

Yes, I know of one.  However, it is an MUA that I seriously doubt
any of your users will use.  I believe all the popular GUI
MUAs will define it.
