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

[hm2k]

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:

# hostname

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

# /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:

# /scripts/updateuserdomains

Thank you.
