【IT168 服务器学院】有台拨号上网的机器，如何在它上面设置postfix使之在拨号成功后可以发送队列中的信件？

　　在postfix站点上有个讨论主题，解决方法是在main.cf中做如下设置：

　　# your ISP''s SMTP server name or IP address goes here
　　relayhost = smtprelay.someprovider.com
　　#
　　# this line disables spontaneous PPP connections
　　defer_transports = smtp
　　#
　　# this line disables dns lookups for mail. As you are using a relay you really don''t need DNS. If you use this you should use an ip address for $relayhost.
　　disable_dns_lookups = yes
　　并在拨号脚本中加入：
　　/usr/sbin/sendmail -q
