DESCRIPTION
This class is the base for various message (and message parts) converters.

Extends "DESCRIPTION" in Mail::Reporter.

  Converters between message objects
Internally, the Mail::Message::coerce() is called when foreign objects are used where message objects are expected. That method will automatically create the converting objects, and re-use them.

•   Mail::Message::Convert::MailInternet

    Converts the simple Mail::Internet messages into Mail::Message objects.

•   Mail::Message::Convert::MimeEntity

    Converts the more complicated MIME::Entity messages into Mail::Message objects.

•   Mail::Message::Convert::EmailSimple

    Converts Email::Simple messages into Mail::Message objects.

  Other converters

•   Mail::Message::Convert::Html

    Plays tricks with HTML/XMHTML without help of external modules.

•   Mail::Message::Convert::HtmlFormatText

    Converts HTML body objects to plain text objects using the HTML::FormatText module.

•   Mail::Message::Convert::HtmlFormatPS

    Converts HTML body objects to Postscript objects using the HTML::FormatPS module.

•   Mail::Message::Convert::TextAutoformat

    Converts a text message into text using Text::Autoformat.

     -Option--Default
      fields  <see description>

    fields => $name|$regex|\@names|\@regexes
        Select the fields of a header which are to be handled. Other fields will not be used. The value of this option is passed to Mail::Message::Head::Complete::grepNames() whenever converters feel a need for header line selection. By default, the "To", "From", "Cc", "Bcc", "Date", "Subject", and their "Resent-" counterparts will be selected. Specify an empty list to get all fields.

  Attributes

  Converting

$obj->selectedFields($head)
    Returns a list of fields to be included in the format. The list is an ordered selection of the fields in the actual header, and filtered through the information as specified with new(fields).

  Error handling

$obj->AUTOLOAD()
    Inherited, see "Error handling" in Mail::Reporter

DIAGNOSTICS

Error: class $package does not implement method $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()
