If the sendmail program finds such a character, it prints the following
warning, ignores that line, and continues to read the configuration file:
/etc/mail/sendmail.cf: line 15: unknown configuration line "v9"
* Note that other versions of sendmail, suchas Sun and IDA, can have more, fewer, or different commands.
