POSTFIX 邮件服务器搭建问题-红联Linux系统门户

以下是我的配置文件,我是centos 5.4 防火墙和SELINUX都是关闭

myhostname = calysc
myorigin = $myhostname
inet_interfaces = all
inet_protocols = ipv4
mydestination = $myhostname, localhost.$mydomain, localhost,
linux.centos.vbird, ftp.centos.vbird
mynetworks = 127.0.0.0/8, 192.168.1.0/24, hash:/etc/postfix/access
relay_domains = $mydestination
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases

------------------------------------
service postfix start 出现以下错误日志:
Nov 15 11:56:10 gzpro1 sendmail[17940]: alias database /etc/aliases rebuilt by root
Nov 15 11:56:10 gzpro1 sendmail[17940]: /etc/aliases: 76 aliases, longest 10 bytes, 765

bytes total
Nov 15 11:56:10 gzpro1 postfix/postfix-script: starting the Postfix mail system
Nov 15 11:56:10 gzpro1 postfix/master[17986]: fatal: bind 0.0.0.0 port 25: Address already

in use
---------------------------------
然后把inet_interfaces = all 改成 inet_interfaces = $myhostname 出现以下错误日志
Nov 15 11:57:58 gzpro1 sendmail[18010]: alias database /etc/aliases rebuilt by root
Nov 15 11:57:58 gzpro1 sendmail[18010]: /etc/aliases: 76 aliases, longest 10 bytes, 765

Nov 15 11:57:59 gzpro1 postfix/postfix-script: starting the Postfix mail system
Nov 15 11:57:59 gzpro1 postfix/master[18056]: fatal: bind 127.0.0.1 port 25: Address

already in use
-----------------------------------
问题1: 到底是出了什么问题,我软件没装好? 我是用yum install postfix 安装的.
还是版本问题? 还是我配置文件写错了吗?

====================我是分割线===========================
另外我输入
[root@gzpro1 ~]# postqueue -p
postqueue: warning: Mail system is down -- accessing queue directly
Mail queue is empty
问题2 : 这又是什么问题?

====================我是分割线===========================
还有我输入
[root@gzpro1 ~]# echo "sss" | mail -s "123" root
[root@gzpro1 ~]# /etc/mail/submit.cf: line 432: readcf: option RunAsUser: unknown user

smmsp
/etc/mail/submit.cf: line 451: readcf: option TrustedUser: unknown user smmsp
Mail submission program must have RunAsUser set to non root user

这时候我没开邮件服务器,应该放入等待列表里面的,但是却出现了这个,是怎么回事呢?
我是新手,请各位大虾帮帮忙解决,跪谢!

来学习一下，最近自己想搭建一个小型的邮件服务器，不知道选什么好。所以来看看

没有同时用，早就关了sendmail了，貌似是依赖问题没有搞好。

alick 于 2011-11-22 12:03:11发表:

sendmail 和 postfix 不能同时用吧，二者都是邮件发送服务器

568040142 于 2011-11-21 13:56:35发表:

OK 现在知道是我的DNS问题了，至于mail是sendmail没有配置好的问题。

calysc.localdomain 这个域名解析不出来啊，所以发不出去，结果bounce（弹回）了

568040142 于 2011-11-18 12:08:52发表:

sendmail大概停掉了。netstat -tunlp | grep sendmail 没有显示。
至于为什么会弹回我也不知道。。
至于外发邮件，我用雷鸟测试了下，发不出邮件，错误日志如下：

alick 于 2011-11-17 23:21:37发表:

我想问楼主的sendmail服务停掉没，怎么还有sendmail的日志消息？
postfix显示几封邮件都被bounced（弹回）了，因为收件人就在本地。
不太清楚为什么会bounce，但楼主有没有试过向外发送邮件是否正常
（比如自己在163的邮箱等）

感谢alick大大的回答但是现在又有新问题了。。
输入 echo "1230" | mail -s "11" root

这是没开postfix 的
Nov 17 17:35:50 gzpro1 sendmail[11838]: pAH9ZoUf011838: from=root, size=27, class=0, nrcpts=1, msgid=<201111170935.pAH9ZoUf011838@gzpro1.guangztr.edu.cn>, relay=root@localhost

求解

引用:
Mail submission program must have RunAsUser set to non root user

这里说 RunAsUser 不能使 root。那就把它改成普通的服务用户。如果系统上有 postfix 用户的话，
就应该是 postfix。

2楼求解

568040142 于 2011-11-16 10:17:43发表:

感谢AILCK的回答,现在postfix能开了,但还是不能使用mail.
输入 echo "123" | mail -s "1" root 出现 Mail submission program must have RunAsUser set to non root user

然后 vim /etc/mail/submit.cf 发现
432行是
# what user id do we assume for the majority of the processing?
O RunAsUser=root

451行是
# Trusted user for file ownership and starting the daemon
O TrustedUser=root

该怎么改？谢谢

alick 于 2011-11-15 21:44:00发表:

系统上sendmail服务开启了，占用了25端口。要使用postfix，先把sendmail关掉：
临时关闭sendmail（当前有效，重启后无效）：[code]service sendmail stop[/code]永久（当前无效，重启后生效）：[code]chkconfig sendmail off[/code]
