SYNOPSIS
  my $cc = Mail::Message::Field::Full->new('Cc');
  my $me = Mail::Message::Field::Address->parse('"Test" <test@mail.box>')
  my $other = Mail::Message::Field::Address->new(phrase => 'Other',
        address => 'other@example.com');

  $cc->addAddress($me);
  $cc->addAddress($other, group => 'them');
  $cc->addAddress(phrase => 'third', address => 'more@any.museum',
    group => 'them');

  my $group = $cc->addGroup(name => 'collegues');
  $group->addAddress($me);
  $group->addAddress(phrase => "You", address => 'you@example.com');

  my $msg = Mail::Message->build(Cc => $cc);
  print $msg->string;

  my $g  = Mail::Message::Field::AddrGroup->new(...);
  $cc->addGroup($g);

DESCRIPTION
All header fields which contain e-mail addresses only. Not all address fields have the same possibilities, but they are all parsed the same: you never know how broken the applications are which produce those messages.

When you try to create constructs which are not allowed for a certain kind of field, you will be warned.

RFC5322 did allow address groups for "To" and "Cc", but not to be used in (amongst other) "From" and "Sender" fields. This restriction got lifted by RFC6854 (2013). <https://www.rfc-editor.org/rfc/rfc6854>

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()"

Warning: field content is not numerical: $content
    The numeric value of a field is requested (for instance the "Lines" or "Content-Length" fields should be numerical), however the data contains weird characters. Cast by "toInt()"

Error: field name too long (max $count), in '$name'.
    It is not specified in the RFCs how long a field name can be, but at least it should be a few characters shorter than the line wrap. Cast by "fold()"

Warning: ignoring addressless phrase '$phrase'.
    Cast by "parse()"

Warning: illegal character in charset '$name'.
    The field is created with an utf8 string which only contains data from the specified character set. However, that character set can never be a valid name because it contains characters which are not permitted. Cast by "encode()"

Warning: illegal character in field name $name.
    A new field is being created which does contain characters not permitted by the RFCs. Using this field in messages may break other e-mail clients or transfer agents, and therefore mutulate or extinguish your message. Cast by "consume()"

Warning: illegal character in language '$name'.
    The field is created with data which is specified to be in a certain language, however, the name of the language cannot be valid: it contains characters which are not permitted by the RFCs. Cast by "encode()"

Warning: illegal encoding '$name', using 'q'.
    The RFCs only permit base64 ("b " or "B ") or quoted-printable ("q" or "Q") encoding. Other than these four options are illegal. Cast by "encode()"

Warning: illegal part in address field $name: $part.
    Cast by "parse()"

Error: no attributes for address fields.
    Is is not possible to add attributes to address fields: it is not permitted by the RFCs. Cast by "addAttribute()"
