de mensajes de correo electr\u00f3nico entre servidores.<\/span><span class=\"pending\"> Servidores,<\/span><span class=\"pending\"> no su cliente de correo electr\u00f3nico como Gmail o Outlook,<\/span><span class=\"pending\"> son los verdaderos caballos de batalla que env\u00edan y reciben correos electr\u00f3nicos.<\/span><span class=\"pending\"> SMTP define la forma en que estos
