    Default Zimbra Hackked

    Hi I really need some help with this. We have been running zimbra without a problem for the last year or so. Today I started to get complaints that we were not being received or sent (no error messages, emails just never arrived).

    I took a look at the email queues and I had 6000 deffered, 4000 incoming and about 20000 active.

    I have stopped postfix, and blocked all access to the zimbra server at the firewall level.

    I really need help in determining my next steps.

    Thanks in advance...

    I'd suggest you start with some of the following threads: +"compromised account" - Yahoo! Search Results +hacked - Yahoo! Search Results

    You need to determine if it's a compromised account and perhaps implement strong password settings for Zimbra accounts.

    Hi and thanks for your help.

    I ran some tests and it looks like I had accidently configured zimbra as an open relay. I undid what I did about a month ago and voila relaying stopped.

    Thanks again.
