Como resolver el error "[ID 702911 mail.crit] My unqualified host name (hostname) unknown" / "[ID 702911 mail.alert] unable to qualify my own domain name (hostname) -- using short name"
Este error suele aparecer por una causa muy sencilla, el archivo /etc/hosts no tiene el dominio correspondiente al nombre del hosts.
Nuestra entrada debería lucir de esta manera:
172.24.0.200 localzone localzone.xyzcorp.ad loghost
Y no de esta:
172.24.0.200 localzone loghost
Esta sencilla modificación resolvería el error.
