    Hi. I need help.
    Some emails aint coming through. I have big people like sony trying to email us .
    see the problem is, that we had the server reformated in December and since then, we can not recieve emails from some people. There are getting roughly the same error. We have reinstalled the mailing service and no luck. We are using Cpanel
    Here are some of the errors(i have changed the domain to mydomain)

    Subject: Warning: message 1HCtdn-0001ze-KN delayed 72 hours

    This message was created automatically by mail delivery software.
    A message that you sent has not yet been delivered to one or more of its
    recipients after more than 72 hours on the queue on llex01.uwic.ac.uk.

    The message identifier is: 1HCtdn-0001ze-KN
    The subject of the message is: Tonight
    The date of the message is: Fri, 2 Feb 2007 08:19:30 -0000
    The subject of the message is: Tonight

    The address to which the message has not yet been delivered is:

    phill@mydomain.co.uk
    Delay reason: SMTP error from remote mailer after RCPT
    TO:<phill@mydomain.co.uk>:
    host media4creative.co.uk [85.234.157.118]: 451 Could not complete
    sender verify callout

    No action is required on your part. Delivery attempts will continue for
    some time, and this warning may be repeated at intervals if the message
    remains undelivered. Eventually the mail delivery software will give up,
    and when that happens, the message will be returned to you.

    Here is another message

    Unknown user: nathaniel@mydomain


    Original message follows.

    Run your domain at dnsreport.com and see if there are any errors. When I have seen these types of strange problems, some mail gets through and others don't, it seems to be a mismatch between the DNS records on cPanel and what is listed at the registrar.

    The reason, as in your post is "Could not complete sender verify callout"

    The sender verify callout routine will try to contact the sending server, and test if the user or sending address actually exists. As some people insist to send with non-existant accounts/users at a particular domain or fail to support callout or other RFCs, you may get occasional sender verify callout 'errors' in your logs.

    Fortunately, there are some things you can do, for instance, turn them off altogether, or use a custom whitelist in your exim conf.

    To turn it off, (assuming you haven't customized exim), go to Main >> Service Configuration >> Exim Configuration Editor and uncheck the checkbox.

    To make a whitelist, you can search these forums, since there is a post on that, not too long ago... Just search for "sender verify callout"
