[CentOS-es] [CentOs-es] Postfix Noob

[Ken Salinas Rodriguez]

Un saludo:

Una consulta, soy principiante, instale CENTOS 5.2, actualice los paquetes
yum update, y deseo instalar poxtfix , para eso previamente desinstalo
sendmail, pero me sale 

rpm -e sendmail-8.13.8-2.el5
error: Failed dependencies:
        /usr/sbin/sendmail is needed by (installed)
redhat-lsb-3.1-12.3.EL.el5.centos.i386
        smtpdaemon is needed by (installed) mdadm-2.6.4-1.el5.i386
        smtpdaemon is needed by (installed) mutt-1.4.2.2-3.0.2.el5.i386
        smtpdaemon is needed by (installed) fetchmail-6.3.6-1.1.el5.i386

Tengo entendido q estan amarrados a sendmail, si lo desinstalo e instalo
inmediatamente postfix no tendre problemas? O no debo desinstalar sendmail?

Saludos Cordiales
