Does this mean:
    Last week somebody got a username/password for an account at your Exim
    server.
?

Now you've changed the passwords of all mail accounts?

Probably want to restrict the logins to a list of certain IPs?
It should be sufficient to restrict the authentication offer to
a list of IPs.

    begin authenticators

    # NOT TESTED!

        plain:
            driver = ..
            server_condition = ${if and{\
                {def:tls_cipher}\
                {match_ip{$sender_host_address}{iplsearch;/etc/exim4/hosts-auth-ok}}}}
