.IX Header "DESCRIPTION"
The body (content) of a message can be stored in various ways.  In this
documentation you find the description of extra functionality you have
when a message is stored in a file.
.PP
Storing a whole message is a file is useful when the body is large.  Although
access through a file is slower, it is saving a lot of memory.

Fatal error: the specific \f(CW$package\fR (or one of its superclasses) does not
implement this method where it should. This message means that some other
related classes do implement this method however the class at hand does
not.  Probably you should investigate this and probably inform the author
of the package.

The data (message body) is encoded in a way which is not currently understood,
therefore no decoding (or recoding) can take place.

A Mail::Message::Body::File object is to be created from a named file, but
it is impossible to read that file to retrieve the lines within.  Therefore,
no copy to a temporary file can be made.
