problem with MTA non working and postfix is not running

[BelluX]

Hi,

i have a problem with my zimbra server, it's a fresh installation, the version is the newest..

the problem it's the mta service and the postfix.

[zimbra@posta root]$ zmcontrol status
Host posta.bellux.it
amavis Running
antispam Running
antivirus Running
dnscache Running
imapd Running
ldap Running
logger Running
mailbox Running
memcached Running
mta Stopped
postfix is not running
opendkim Running
proxy Running
service webapp Running
snmp Running
spell Running
stats Running
zimbra webapp Running
zimbraAdmin webapp Running
zimlet webapp Running
zmconfigd Running

i'm a newbie and this is my first installation, how i can resolve this? If i telnet the 25, i didn't receive any response.

the firewall is set with this command: "firewall-cmd --permanent --add-port={25,80,110,143,443,465,587,993,995,5222,5223,9071,7071}/tcp"

these are the response of the record A and MX.

[root@posta ~]# dig -t A posta.bellux.it

Thank you.

Hi,

It seems that you "may" be facing 2 issues:
A. Your postfix services are not starting
B. You may be having some NAT/DNS problems

A. You should find in /var/log/zimbra.log some clue why that service is not starting. You could try.
1. Stopping zimbra services
$ zmcontrol stop

1b. Make sure nobody is using port 25 (shoudn't be the case as your telnet is not answering).
$ netstat -vnpteua | grep 25

2. Once all services are down, start capturing logs for further analysis
$ tail -f /var/log/zimbra.log > /tmp/there_was_an_start_attempt.txt

3. Open another window or send the previous process to the bg...whatever you are confortable doing.

4. Start zimbra services
$ zmcontrol start

5. Once that command finished, stop the log capturing.

6. Read that log (shouldn't be too long) searching for anything that gives you a clue about why that service is not starting.

B. What your /etc/hosts and /etc/resolv.conf files look like?
