Hello,

One of the email accounts on our email server is receiving hundreds of SPAM emails per day. In the last two or three weeks, there have been 3000+ SPAM messages. These are all coming to one account - the other email addresses are fine.

I tried lowering the spam settings, and at one point had them as low as 1 and 10. There were still messages getting into the inbox.

Where should I look to update spam rules? I downloaded a few SARE rule files into the folder and rebooted, but it doesn't look like much has changed.

Here are some examples of the SPAM:

I'd like to stay away from installing additional non-zimbra software packages unless they've been proven stable. I have a really stable system at this point and don't want to break it. I do have to do something about the SPAM though.

Please offer suggestions. Thanks!
