It should work on any version of perl released in the last five years. Although it may work on older versions of perl, no guarantee is made that the minimum required version will not be increased. The version may be increased for any reason, and there is no promise that patches will be accepted to lower the minimum required perl. =head1 METHODS =head2 easy_transport my $transport = Email::Sender::Util->easy_transport($class => \%arg); This takes the name of a transport class and a set of args to new. It returns an Email::Sender::Transport object of that class. C<$class> is rewritten to C<Email::Sender::Transport::$class> unless it starts with an equals sign (C<=>) or contains a colon. The equals sign, if present, will be removed. =head1 AUTHOR Ricardo Signes <cpan@semiotic.systems> =head1 COPYRIGHT AND LICENSE This software is copyright (c) 2022 by Ricardo Signes.
