    This is expected behavior. Can you try telnet to 127.0.0.1 on 10025 ?

    telnet 127.0.0.1 10025
    Dear veronica, my server (zcs 7.2 on centos 5.3 ) now acting like this all mails incoming and outgoing are deferred. And i can't telnet to 10052 ports ..
    I was upgrading from zcs 7.0 to 7.2 and this occurs ..
    Regards.

    Read the error messages you receive, it tells you what the problem is then search these forums and internet for an answer.

    Why have you done that, what do you actually mean by "DNS checking", why do you think that will solve your problem and did you fix the problem that's shown in your previous error?

    This error message also tells you that the problem is caused by it not being able to connect to that server, it times out.
