lost connection after CONNECT from smtp4.mail.ru[94.100.176.44]

[NODE49]

Hi all!

I just installed Zimbra CS 7.1.4 and set up domains. Now i can send mail from Zimbra to my mailbox in free mail hosting mail.ru but when i reply the messages do not reach mailbox and i see in logs this:

Feb 8 16:21:24 mx postfix/smtpd[12693]: connect from smtp4.mail.ru[94.100.176.44]
Feb 8 16:21:24 mx postfix/smtpd[12693]: lost connection after CONNECT from smtp4.mail.ru[94.100.176.44]
Feb 8 16:21:24 mx postfix/smtpd[12693]: disconnect from smtp4.mail.ru[94.100.176.44]

I have simple mail server (postfix+dovecot) and it works great. Now i'd like to try zimbra but i cant solve this problem...

PS I thought it is something wrong with zimbra`s postfix main.cf - by default it was mydomain=localdomain. I changed it to my real domain an make "postfix reload" but this solves nothing

I'll move this to the correct forum as it's not a question aboit Installation of Zimbra (which is where you posted).

Is this server behind a firewall and/or NAT router? If it is, have you set-up a Split DNS (you should)? Whether you have a Split DNS or not, post the output of all the commands in the 'Verify...' section of that article.

Yes, this server is behind the NAT router. I just have done set-up masqdns like in Split DNS, but this not helped me. I still have this in zimbra.log:

Feb 9 13:43:03 mx postfix/smtpd[58613]: connect from smtp20.mail.ru[94.100.176.173]
Feb 9 13:43:03 mx postfix/smtpd[58613]: lost connection after CONNECT from smtp20.mail.ru[94.100.176.173]
Feb 9 13:43:03 mx postfix/smtpd[58613]: disconnect from smtp20.mail.ru[94.100.176.173]

PS The server has an internal address 192.168.78.19 and name mx. kirov.rus.coop is real domain name.

You haven't posted the output of all the commands in the verify section, it's needed to verify your configuration.

Anyone have ideas?..

[NODE49]

I tried this:

zimbra@mx:~/postfix-2.7.7.3z/conf$ postconf -d | grep mydomain
append_dot_mydomain = yes
mydestination = $myhostname, localhost.$mydomain, localhost
mydomain = localdomain

^^^^^^^^^^^^^^^ - may be this is my problem? But how to change this? In my main.cf there is "mydomain = kirov.rus.coop" but why 'postconf -d' tells me it is 'localdomain'?..

The one thing you haven't posted aboce is the /etc/hosts file, what does it contain.

Sure, here it is:

zimbra@mx:~/postfix-2.7.7.3z/conf$ cat /etc/hosts
127.0.0.1       localhost.local localhost
192.168.78.19   mx.kirov.rus.coop mx

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

When i try to establish telnet session on port 25 from my LAN to zimbra server, postfix tell me

220 mx.kirov.rus.coop ESMTP Postfix

and wait for dialog, but when i try the same from Internet, postfix tell me nothing. Just blank screen and no reactions on any coomand except CTRL+]. Is this a zimbra`s postfix config trouble or incorrect DNS settings? What should i try to fix?
