[Postfix-es] Resultados de la resolucion inversa al leer o al enviar

[Salman ®]

Hola, tengo un usuario con una IP que hace las cosas mas extrañas.

No se si lo hace su IP o lo hace PostFix claro :-)

El caso es que cuando el usuario va a leer su buzon, PostFix hace la resolucion inversa de su IP correctamente, pero cuando lo que hace el usuario es intentar enviar un correo, entonces PostFix no hace la resolucion inversa de esa misma IP mostrando un "unknow",

Pidiendo directamente al servidor la resolucion la muestra correctamente.

¿ De que puede ser ? ¿ Alguna idea ?
