Problems sending e-mail after installation

[genesup]

Hello,

I`ve successfully installed Zimbra on my server. I can use web-interface to write a letter, but then I get this error sending it:

method:	SendMsgRequest
msg:	try again: Unable to connect to the MTA
code:	mail.TRY_AGAIN

      version: "6.0.4_GA_2038.SLES11_64"
     }
   }
 }

This is strange since, to my understanding, I do not need an MTA to SEND an e-mail.

Nevertheless, I have made all the necessary steps to configure my DNS.

/etc/resolve.com:
nameserver abs.cmm.msu.ru
search cmm.msu.ru

abs:/var/lib/named/master # host -t mx abs.cmm.msu.ru
abs.cmm.msu.ru mail is handled by 10 abs.cmm.msu.ru.

abs:/var/lib/named/master # host -t a abs.cmm.msu.ru
abs.cmm.msu.ru has address 195.208.219.98

Zimbra MTA is set as follows:
Web mail MTA Hostnames: abs.cmm.msu.ru
Web mail MTA Port: 25
Web mail MTA timeout (s): 60s
MTA Trusted Networks: 127.0.0.0/8 195.208.219.0/24 192.168.168.0/24
Enable DNS lookups = yes

Though i still have the same error.


Please help me with this.

I'm sure you know this but you've installed Zimbra on an unsupported platform.

Post the output of the following commands (run on the zimbra server):

zmcontrol status

cat /etc/hosts
cat /etc/resolv.conf
dig yourdomain.com mx
dig yourdomain.com any
host `hostname` <-- use that exact command with backticks not single quotes

Thank you for quick reply

Your hosts file is incorrect, follow the instructions in the Quick Start Installation Guide (those details also apply to openSUSE). You also have probably got Postfix enabled and started, disable it from starting on boot and kill the currently running version. When you've done that and fixed your hosts file (post the details of the changes you make) restart Zimbra.

[genesup]

I`ve disabled Postfix deamon using those commands:

zmlocalconfig -e postfix_enable_smtpd_policyd=no
zmprov mcf -zimbraMtaRestriction "check_policy_service unixrivate/policy"
postfix stop

Then I changed my hosts file
(actually, I do not see much difference)

127.0.0.1    localhost.cmm.msu.ru localhost
195.208.219.98  abs.cmm.msu.ru abs
127.0.0.2       abs.cmm.msu.ru abs
192.168.168.8   abs
192.168.168.103 leiden
192.168.168.5   irina
192.168.168.12  kirilin
192.168.168.66  arzhanik
192.168.168.54  arzhanik-nb
192.168.168.203 win2003

Then I stopped all services

zimbra@abs:~> zmcontrol shutdown
Host abs.cmm.msu.ru
        Stopping stats...Done.
        Stopping mta...Done.
        Stopping spell...Done.
        Stopping snmp...Done.
        Stopping archiving...Done.
        Stopping antivirus...Done.
        Stopping antispam...Done.
        Stopping imapproxy...Done.
        Stopping memcached...Done.
        Stopping mailbox...Done.
        Stopping logger...Done.
        Stopping ldap...Done.

Then I started all services

zimbra@abs:~> zmcontrol startup
Host abs.cmm.msu.ru
        Starting ldap...Done.
        Starting logger...Done.
        Starting mailbox...Done.
        Starting antispam...Done.
        Starting antivirus...Done.
        Starting snmp...Done.
        Starting spell...Done.
        Starting mta...Done.
        Starting stats...Done.

And then ... I got absolutely the same error when sending message from :
method: SendMsgRequest
msg: try again: Unable to connect to the MTA

What do you suggest?

Thank you.

[genesup]

Can anyone suggest something?

Thank you.

Your hosts file is still incorrect, it should look like this (as per the Documentation:

127.0.0.1    localhost.localdomain localhost
x.x.x.x  abs.cmm.msu.ru abs

The IP address on the second line should be the LAN IP of your server, unless it really is on a public IP. Have you also disabled AppArmor on this server?

[genesup]

yes it is really on a public IP. Its all-in-one: DNS and DHCP for LAN and mail server at the same time.
Why is it a problem? Is it so much unsafe?

Thank you.

My advice would be to keep the server behind a firewall or NAT router and forward the required ports to Zimbra, it's not advisable to run a firewall or AppArmor on a Zimbra server (you havn't said if that's the case) but it does need protection.

I notice what you've also done is use a sub-domain for this server and also used that for the FQDN of the server. What you should do is give the server a FQDN such as (for example) "mail.abs.cmm.msu.ru" and you hosts file would contain the line:

x.x.x.x mail.abs.cmm.msu.ru mail <- obvious the LAN IP

You'd obviously need to change your internal DNS records to reflect that configuration (as described in the Split DNS set-up).
