Problema configuración mutt multiples cuentas

[adroc2]

Buenos días, estoy intentando configurar mutt para conectarse a diversas cuentas.

Tengo las configuraciones en distintos archivos, los cuales cargo mediante una macro. No obstante, a pesar de que carga las configuraciones, me sigue mostrando los mensajes de la primera cuenta. Alguna idea de por que?
