NAME

6       Mail::Message::Body::Nested - body of a message which contains a
7       message

INHERITANCE

10        Mail::Message::Body::Nested
11          is a Mail::Message::Body

SYNOPSIS

15        See Mail::Message::Body
16
17        if($body->isNested) {

DESCRIPTION

23       The body (content) of a message can be stored in various ways.  In this
24       manual-page you find the description of extra functionality you have
25       when a message contains a nested message, like "message/rfc822".
26
27       A nested message is different from a multipart message which contains
28       only one element, because a nested message has a full set of message
29       header fields defined by the RFC882, where a part of a multipart has
30       only a few.  But because we do not keep track whether all fields are
31       presented, a "Mail::Message::Part" is used anyway.
32

DIAGNOSTICS

330       Warning: Charset $name is not known
331           The encoding or decoding of a message body encounters a character
332           set which is not understood by Perl's Encode module.
333
334       Warning: No decoder defined for transfer encoding $name.
335           The data (message body) is encoded in a way which is not currently
336           understood, therefore no decoding (or recoding) can take place.
337
338       Warning: No encoder defined for transfer encoding $name.
339           The data (message body) has been decoded, but the required encoding
340           is unknown.  The decoded data is returned.
341
342       Error: Package $package does not implement $method.
343           Fatal error: the specific package (or one of its superclasses) does
344           not implement this method where it should. This message means that
345           some other related classes do implement this method however the
346           class at hand does not.  Probably you should investigate this and
347           probably inform the author of the package.
348
349       Warning: Unknown line terminator $eol ignored
350       Error: You cannot use foreachLine on a nested
351           foreachLine() should be used on decoded message bodies only,
352           because it would modify the header of the encapsulated message.
353           which is clearly not acceptable.
