    Default Tons of messages like this

    Hi all.
    After i installed the new Zimbra Community Edition, 8.0 GA 5434, for two times (at a month interval) i was flooded with tons of messages like this:

    Received: from ns.alexvoicu.eu (89.33.12.206) by FMWDMAIL.NTDFMWD.local (10.0.0.16) with Microsoft SMTP Server id 14.1.379.0;

    It looks like spammers tried to use my server to send unauthorized mails using smtps (465) port, but because i have authentication activated the messages are put in bounce, defer and deferred folders and the server even don't crash are significantly slow down.
    And by the way, isn't open relay server...
    And for statistics... max number of messages was 1669731

    Can anyone have an ideea about this problem???

    Thanks for your support.

    Default

    activate the cbpolicy server and use the graylisting module, or sipmly install postgrey and use with zimbra.
