Another thing about this, postfix fails on startup:
Feb 9 00:49:57 x800 postfix[1387]: warning: valid_hostname: invalid
character 13(decimal): x800.mydomain.local?
Feb 9 00:49:57 x800 postfix[1387]: fatal: unable to use my own hostname
Feb 9 00:49:59 x800 postfix/sendmail[1471]: warning: valid_hostname:
invalid character 13(decimal): x800.mydomain.local?
Feb 9 00:49:59 x800 postfix/sendmail[1471]: fatal: unable to use my
own hostname
Because some CentOS system file is corrupted?
After setting "hostname x800.mydomain.local" postfix starts normally.
