    Default big problem with mail deferred

    hello,
    we have ZCS 5.02 in ubuntu 6.06, when I check in the:
    web console>Mail Queues>mail.domain.com>Deferred
    when we try send a email to user@cantv.net, we find the next error

    host relay.cantv.net[200.44.32.36] said: 421 4.4.1 collect: read timeout on connection from mail.domain.com from=<user@domail.com> (in reply to end of data command)

    in /var/log/zimbra.log:

    Jun 11 16:05:53 mail postfix/smtp[7114]: E538898813F: to=<receive.user@domail.com>, relay=relay.cantv.net[200.44.32.36]:25, delay=5275, delays=5143/0.28/2.8/129, dsn=4.4.1, status=deferred (host relay.cantv.net[200.44.32.36] said: 421 4.4.1 collect: read timeout on connection from mail.domain.com, from=<sender.user@domain.com> (in reply to end of DATA command))

    thank for you attention

    Is this a new install or an upgrade? Are you behind a NAT router and do you have a Split DNS installed? Has this only just started happening and what changed to make it happen? Are all the zimbra services running? Has something changed on the server that you are using as a relay?
    Regards

    If you are still having issues would you be so kind as to post the following
    Code:
    cat /etc/hosts
    cat /etc/resolv.conf
    dig _yourZCSFQDN_
    dig _yourdomainname_ mx
    host `hostname` <- note backticks and not double quotes

    well I already install the server, I am behind a NAT router, and I did the split domain, all services are running, I didn't change anything in the server

    root@mail:~# cat /etc/hosts
    127.0.0.1 localhost
    192.0.0.171 mail.domail.com mail

    # The following lines are desirable for IPv6 capable hosts
    ::1 ip6-localhost ip6-loopback
    fe00::0 ip6-localnet
    ff00::0 ip6-mcastprefix
    ff02::1 ip6-allnodes
    ff02::2 ip6-allrouters
    ff02::3 ip6-allhosts

    root@mail:~# cat /etc/resolv.conf
    search domain
    nameserver 192.0.0.171
    nameserver 216.72.131.5
    nameserver 216.72.131.6

    root@mail:~# dig domain.com

    root@mail:~# host `hostname`
    mail.domain.com has address 192.0.0.171

    NOTE: the problem is with only some domain, but i can send and receive from gmail, yahoo, hotmail, and others

    thank for you help
