NAME

Mail::Message::Body::File - body of a message temporarily stored in a file

INHERITANCE

Mail::Message::Body::File
  is a Mail::Message::Body
  is a Mail::Reporter

SYNOPSIS

See Mail::Message::Body

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.

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.

DIAGNOSTICS

Error: Cannot write to temporary body file $filename: $!

The message body is to be stored in a temporary file (probably because it is a large body), but for the indicated reason, this file cannot be created. Cast by new()

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. Cast by encode()

Warning: Content-Transfer-Encoding `$encoding' requires explicit charset, defaulted to utf-8

Cast by encode()

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. Cast by encode()

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. Cast by encode()

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. Cast by notImplemented()

Error: Unable to read file $filename for message body file: $!

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. Cast by new()

Warning: Unknown line terminator $eol ignored

Cast by eol()
