    We've recently moved a bunch of users from one server to another.

    However, whenever this user tries to send/receive email, they continually prompted with the "Enter Network Password" dialogue window.

    I reset the password via cPanel so I know the password is correct but it still would not accept it.

    So I checked /var/log/maillog on the server which shows lots of entries that look like this:

    This is repeated lots of times and the user never gets any mail.

    I've never come across this before.

    Any ideas?

    Hello :)

    Please ensure the hostname of the server does not match a domain name associated with an account. You can check the hostname via the following command:

    # hostname
    Then, check to see if it exists as an account:

    # /scripts/whoowns
    It's fine if the hostname is a subdomain that does not exist (e.g. where is an account), however the hostname should never be used as a domain name for an account.

    Beyond that, you can try running the following command:

    # /scripts/updateuserdomains
    Thank you.
