运行sendmail配置时*** ERROR: FEATURE() should be before MAILER()错误 解决方法

*** ERROR: FEATURE() should be before MAILER()
*** MAILER(`local') must appear after FEATURE(`always_add_domain')*** ERROR: FEATURE() should be before MAILER()
*** MAILER(`local') must appear after FEATURE(`allmasquerade')*** ERROR: FEATURE() should be before MAILER()

修改sendmail.mc最后几行
vi /etc/mail/sendmail.mc
将文档中的
MAILER_DEFINITIONS
MAILER(`local')dnl
MAILER(`smtp')dnl
放到文档最后
