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.
WARNING: Since 2023, at least outlook started to interpret RFC6533 incorrectly. Bodies of
type 'message/rfc822' can only be 'nested', but when they (illegally) have Content-
Transfer-Encoding, they can now behave like normal message parts (the same as a pdf or
image).

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.
