Hello, I'm new to Zimbra and I have it installed for a small comapny of about 10 users. I have read that when you delete emails as spam they only get moved to the spam folder. I have also messed around with the tag and spam settings and have the spam tag set to 60 and the tag set to 20 which started working better for a while, but now I'm getting more and more spam. I have read you can feed spam and ham to the server, but I haven't been able to find a how-to or documentation on how to do this.
If anybody knows where I can find this or just explain how to do this would be great.

Thank you..
