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

    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.
    Regards

    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.

    PPS root@mx:/var/log# dig kirov.rus.coop mx

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

    I tried this:
    Code:
    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'?..

    Sure, here it is:
    Code:
    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
    Code:
    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?
