NAME

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

INHERITANCE

 Mail::Message::Body::Nested
   is a Mail::Message::Body
   is a Mail::Reporter

SYNOPSIS

 See Mail::Message::Body
 if($body->isNested) {
    my $nest = $body->nested;
    $nest->delete;
 }

DESCRIPTION

The body (content) of a message can be stored in various ways. In this manual-page you find the description of extra functionality you have when a message contains a nested message, like "message/rfc822".

A nested message is different from a multipart message which contains only one element, because a nested message has a full set of message header fields defined by the RFC882, where a part of a multipart has only a few. But because we do not keep track whether all fields are presented, a "Mail::Message::Part" is used anyway.

DIAGNOSTICS

Warning: Charset $name is not known: The encoding or decoding of a message body encounters a character set which is not understood by Perl's Encode module.
Warning: No decoder defined for transfer encoding $name.: The data (message body) is encoded in a way which is not currently understood, therefore no decoding (or recoding) can take place.
Warning: No encoder defined for transfer encoding $name.: The data (message body) has been decoded, but the required encoding is unknown. The decoded data is returned.
Error: Package $package does not implement $method.: Fatal error: the specific package (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.
Warning: Unknown line terminator $eol ignored
Error: You cannot use foreachLine on a nested: foreachLine() should be used on decoded message bodies only, because it would modify the header of the encapsulated message. which is clearly not acceptable.
