Em um dos servidores da nossa empresa, de repente / usr / lib / sendmail parou de funcionar.
Nós temos uma chamada para ele em poucos scripts (pertencentes e executados pelo oracle user) e nenhum deles é capaz de enviar um email, mesmo manualmente não funciona.
o servidor é: SunOS 5.10 Generic_Virtual sun4v sparc sun4v
oracle:/home/oracle $ ls -ltr /usr/lib/sendmail
-r-xr-sr-x 1 root smmsp 1064920 Jan 16 2013 /usr/lib/sendmail
Abaixo do exemplo de uma tentativa de enviar emails:
cat /etc/hosts | /usr/lib/sendmail -f [email protected] -t [email protected]
Esta é a saída no modo detalhado:
oracle@myserver:/home/oracle $ cat /etc/hosts | /usr/lib/sendmail -v -f [email protected] -t [email protected]

Além disso, eu dei uma olhada em / var / log / syslog e não consegui encontrar nenhuma mensagem de erro / aviso, apenas mail.info, e é isso que eu encontrei em / var / mail / oracle
