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:

dovecot: auth(default): Failed to lookup domain owner of 3xxxxxx.net
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:

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

Code:
# /scripts/whoowns hostname.com
It's fine if the hostname is a subdomain that does not exist (e.g. server.domain.com where domain.com 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:

Code:
# /scripts/updateuserdomains
Thank you.
