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
