    Default How to find the source of spam

    Hi,
    at present I have around 20000 email in postfix queue.
    I'm using zcs-7.1.0_GA
    How can I find the authenticated user that as been hacked?

    And how can I mass-remove messages from a specific sender?
    Thank you very much

    Hi,
    i think this command could help you:

    grep sasl /var/log/maillog

    you should be able to see which user sends so many emails.
    Also you can see the client ip address near the username, if it's a strange ip it'll be definitely the cause of the problem.

    To mass-remove messages from a specific user you can go into the admin console, under "Queues", and select the server.
    Now right click the sender of the spam messages and select "Delete".

    Regards
