mta and postfix can not work

[wildhuman]

Hi,
I have installed Zimbra network Collaboration(3.1) suite succesfully on fedora 4.
But the thing is when I type
$zmcontrol start
$zmcontrol status
mta stopped
postfix is not running
(other is running)

my /etc/hosts is
127.0.0.1 localhost.localdomain localhost
192.168.0.111 mail.localhsot.localdomain mailhost

and when I type
$postfix start
it displays
postfix/postfix-script:warning:not owned by root:/opt/zimbra/postfix-2.2.9/conf/main.cf
postfix/postfix-script:staring the Postfix mail system
You have new mail in /var/spool/mail/zimbra

and I use "tail -f /var/log/zimbra.log", it displays
fatal:Queue report unavailable - mail system is down
warning:not owned by root:/opt/zimbra/postfix-2.2.9/conf/main.cf
staring the Postfix mail system
fatal:bind 0.0.0.0 port 25:Address already in use

When I use "telnet localhost.localdomain 25", it displays
Trying 127.0.0.1
Connected to localhost.localdomain (127.0.0.1)
Escape character is '^]'
220 mail.localhost.localdomain ESMTP Sendmail 8.13.4/8.13.4; Sat, 12 Aug 2006 00:48:23 -0400

I use "ps aux|grep mta" and ps aux|grep postfix, no more other mta or postfix is running

I searched the forum, but i can not find a method to fix problem, please help me.

Howdy,

Well, it does look like something is hogging up port 25, your mail port.

Perhaps instead of grepping for 'mta' and 'postfix', do a 'ps aux|grep sendmail'.

Sendmail is the default for RedHat/CentOS at the moment, so if you're running one of those, there's an excellent chance sendmail managed to get started somehow.

If so, you can just run:

/etc/init.d/sendmail stop

Good luck,
-Eric

Hi, guy, thanks.

Yes, after stopping the sendmail, it is ok.

And I have a new questions: how setup a DNS in linux? or where can I find some document to set DNS? I knew it is not problem about linux, I just want to try it.

Thanks again.

That depends on whether your running a test server or it's behind a NAT router or need split-dns. Install BIND and have a look at the instructions here there's also some further info in the wiki.
