在Ubuntu 12.04上,我尝试使用dpkg-set-selections在已部署的计算机上自动配置postfix,具体如下：
debconf-set-selections <<EOF postfix postfix/main_mailer_type select Satellite system postfix postfix/root_address string admin@mydomain.org postfix postfix/mailname string mydomain.org postfix postfix/relayhost string gw.mydomain.internal postfix postfix/destinations string $(hostname -f),localhost EOF DEBIAN_FRONTEND=noninteractive apt-get install postfix mailutils
不幸的是,配置程序坚持将mydomain.org添加到postfix / destinations(aka mydestinations)配置参数：
postfix postfix/destinations string mydomain.org,myserver.mydomain.internal,localhost
如何正确配置？我希望任何不合格的邮件都以user@mydomain.org的形式发送,并通过smarthost进行中继.
我认为问题出在安装脚本中,postfix.preinst有一些有趣的代码,还有一些注释：
Add a ‘mydomain’ entry in main.cf for upgrade? Postfix version 2.3.3-2 and later require changes in main.cf. Specifically,mydomain must be specified,since hostname(1) is not a fully qualified domain name (FQDN). . Failure to fix this will result in a broken mailer. Decline this option to abort the upgrade,giving you the opportunity to add this configuration yourself. Accept this option to automatically set mydomain based on the FQDN of the machine.*
