I am a newbie on Zimbra. We have setup zimbra server for the emails but most of the users important emails are going into the Junk Mail folder due to the Antispam Filter. I have found the Spam checking Settings in Global Settings – AS/AV. Could someone tell me what are the best Kill Percent & Tag Percent? So that we got the important emails and get rid of the Junk mails. Currently its Kill Percent = 50 & Tag percent = 20.
Also tell me how it actually works. Should I increase the percentages or decrease it to control the spam. I really appreciate if some could help me in this regard.
