Arranque lento de Sendmail – unqualified host name sleeping for retry

Revisando un servidor que tenía problemas de disco, me he encontrado con un Sendmail que tardaba una barbaridad en arrancar, en un primer momento, y dado que el servidor tenía problemas de rendimiento he pensado que todo se debía a eso..

Una vez el servidor ha estado controlado, he procedido a hacer un restart del servicio Sendmail y el problema de lentitud seguía dándose, por lo que revisando los logs, se podía observar:

Al parecer Sendmail busca un nombre de dominio (FQDN) nuestro nombre ServerTest no lo es… de ahí el tiempo que tarda en arrancar, está consultando y no obtiene resultado.

Para solventarlo podemos realizar un pequeño cambio en el fichero /etc/hosts, en este momento será similar a:

Realizando el siguiente cambio evitaremos el problema, ya que Sendmail ya reconocerá el nombre como FQDN
