[postfix-es] altermime duplica correo

[mlorente]

Buenos días, tengo un postfix mail_version = 2.6.6 sobre CentOS release 
6.4 (Final) al que le aplicado altermime para firmar correos. El proceso 
funciona bien, salvo por el hecho de que se genera un correo adicional 
vacío cuando pasa por el script del disclaimer. Este correo rebota como 
no entregado al no existir el destinatario y se intenta mandar al 
usuario ???

Desactivo el altermime y funciona con normalidad. ¿De donde puede estar 
sacando la segunda dirección de envío?

Gracias.
