[Hilos de Discusión] [Fecha] [Tema] [Autor]Al servidor de un cliente le empezo a pasar algo raro hoy al medio dia: de repente a root le empezaron a llegar decenas (quizá centenas) de "rebotes" de correos, como si "root" estuviera enviando correos a un usuario inexistente. Aquí les "pego" uno de los mails, como ejemplo. NOTA: estoy sustituyendo el nombre real del dominio por uno ficticio, para no "quemar" a mi cliente :-) Es decir, donde dice "ficticio.com" debería decir el dominio de mi cliente. Todos los demás dominios e IPs son reales Que podrá ser? Aquí va el "rebote" como me aparece en Pine: Date: Tue, 15 Oct 2002 23:32:53 -0500 From: Mail Delivery Subsystem <MAILER-DAEMON en www ficticio com> To: postmaster en www ficticio com Subject: Postmaster notify: Host unknown (Name server: 200.56.75.28: host not found) Parts/Attachments: 1 Shown 8 lines Text 2 Shown 305 bytes Message, "Delivery Status" 3 Shown 3.6 KB Message, "Returned mail: User unknown" 3.1 Shown 16 lines Text 3.2 Shown 384 bytes Message, "Delivery Status" 3.3 Shown 1.7 KB Message, "FW : Âà±Hµ¹ cremation °Ñ¦Ò¬Ý¬Ý" 3.3.1 Shown ~495 bytes Text (charset: Unknown) ---------------------------------------- The original message was received at Tue, 15 Oct 2002 23:32:53 -0500 from localhost ----- The following addresses had permanent fatal errors ----- <whitney@200.56.75.28> ----- Transcript of session follows ----- 550 <whitney@200.56.75.28>...
