    Default [SOLVED] Deferred, mail transport unavailable

    A couple of days ago the deferred queue started to grow.

    Checking the /var/log/zimbra.log I found several records like this:

    mail postfix/smtp[14875]: D15641A802A4: to=<info@domain.tld>, relay=none, delay=1198, delays=1198/0.02/0/0, dsn=4.4.1, status=deferred (connect to[]: Connection refused)
    mail postfix/qmgr[8273]: EE5371A80297: to=<info@domain.tld>, relay=none, delay=1200, delays=1199/0.48/0/0, dsn=4.3.0, status=deferred (mail transport unavailable)
    *All domain names and public ips replaced for privacy

    I know these mails origins from another box with smtp mail function sent using a standard form.

    I made sure I can telnet to port 25 on localhost and send mail and I've read others posts for hours and hours and I cant locate the problem.

    postconf mynetworks
    mynetworks = is not the servers IP but instead the networks broadcast.

    cat /etc/resolv.conf
    options rotate
    options timeout:3
    nameserver is the mail servers IP. I'm also running BIND and named is up and running.

    cat /etc/hosts        localhost.localdomain   localhost          mail
    zmcontrol status
            antispam                Running
            antivirus               Running
            ldap                    Running
            logger                  Running
            mailbox                 Running
            mta                     Running
            snmp                    Running
            stats                   Running
    Also, when viewing the tooltip information in Zimbra Webinterface I see this in the deferred mail row.

    From host: localhost.localdomain
    From domain:
    From IP:
    Recipients: info@domain.tld
    To domain: domain.tld
    Content filter: undefined
    Size: 4404
    Reason: connect to[]: connection refused
