Oss.: BIOS was displayed normally !
1) Monitor in Standby
2) SSH available
3) System booted “correctly” (except graphics)
I get this error in /var/log/syslog

Check if sendmail is compiled with TLS (for encryption) and SASL (for authentication). This is the command to use to check it.
#/usr/sbin/sendmail -d0.1 -bv root
You must read something like “Compiled with…STARTTLS”
Att.: If you’ve installed sendmail using yum, TLS support is present !
Install all these packages
# yum install sendmail sendmail-cf cyrus-sasl-plain cyrus-sasl-md5
# cd /etc/pki/tls/certs
# make sendmail.pem
