=head1 NAME

Mail::AuthenticationResults::Header::AuthServID - Class modelling the AuthServID part of the Authentication Results Headerr

=head1 VERSION

version 2.20210112

=head1 DESCRIPTION

The AuthServID is typically the first section of an Authentication Results Header, it records
the server responsible for performing the Authentication Results checks, and can additionally hold
a version number (assumed to be 1 if not present).

Some providers also add additional sub entries to the field, hence this class is capable of
being a parent to version, comment, and sub entry types.

This class is set as the value for a Mail::AuthenticationResults::Header class.

Please see L<Mail::AuthenticationResults::Header::Base>
