    Hi guys,

    I've just noticed over 8000 emails being sent to random yahoo addresses,etc. and error messages coming through to admin account with the following:

    Time: Fri Jul 5 17:17:41 2013 +0200
    Type: AUTHRELAY, Remote IP - (UA/Ukraine/-)
    Count: 107 emails relayed
    Blocked: No

    Any idea how to stop this from happening completely.

    Here is what I've done so far.

    1. Enabled DKIM on all accounts
    2. Turned off - Allow Plaintext Authentication (from remote clients)
    3. Set LFD to block it after a certain number via CSF
    4. Disabled domain account holder password to login into any email accoutn via Tweak Settings.

    Anything else?

    Hello :)

    I recommend reviewing the email headers of these messages to see if you can determine the source of the messages. The following document also includes some useful information how to prevent email abuse:

    Thank you.
