Net::SSLGlue anstelle von Net::SMTP::TLS verwenden

Net::SMTP::TLS enthält momentan einen unschönen Bug[1], der mit
aktuellen Versionen von IO::Socket::SSL zusammen zu einer Exception
führt. Anscheinend wird Net::SMTP::TLS auch schon seit Jahren nicht
mehr gepflegt.

Net::SSLGlue::SMTP (Teil von Net::SSLGlue) erweitert dabei das
Net::SMTP-Interface um TLS-Befehle und ist damit zusätzlich näher am
Net::SMTP-Interface, als es Net::SMTP::TLS je war.
