Problem: every email sent is reported-the meeting record is as follows -example.com 554 5. 0. 0 MX list. Point to example.com. 554 5.3.5 . Local configuration error.
解决的办法是：在/etc/mail/sendmail.cf中把Cwlocalhost修改为Cwexample.com。
然后重新启动sendmail/etc/init。d/发送邮件停止然后start(Solaris 8)/etc/RC。d/初始化。d/sendmail重新启动(Linux)
