Every day I must deal with a large number of e-mails. But, spam has brought me many problems. Oh, my GOD! I had used some software, but they did not play a role. I didn’t give up. Where there is the will, there is the way! At last, I’m lucky that I find SpamAssassinhttp://www.globalshareware.com/Internet/Plesk-colon-SpamAssassin-Support.html! Excellent! ：）

SpamAssassin can help me delete many junk e-mails and I can save a lot of time. It's so nice, easy, quick and reliable. Add the SpamAssassin Anti-SPAM management interface to my Plesk software. Activating this on my license adds an additional Spam filter to my system that is configurable Server-wide or at the domain level. SpamAssassin is an open source mail filter to identify spam. Using its rule base, it uses a wide range of heuristic tests on mail headers and body text to identify ""SPAM"".SpamAssassin as a mail content filter. This tool is completely customizable by and for each user. These instructions tell you how to filter email, disable spamassasin, customize the tagging, and delete spam on the mail server. 

SpamAssassin assigns a score to each of my messages based on whether the message contains certain elements typically contained in spam messages. The resulting score is compared against a threshold. If the score is above the threshold, the message is tagged as spam.  If the score is below the threshold, the message is not tagged as spam. The default threshold is 6. If generally too many messages you receiving are mistakenly identified as spam, simply adjust the threshold to a higher number.  This will also have the effect of not tagging some spam message as spam. This is why I’ve just love it.

If you have encountered a problem as I do, you should as quickly as you can install the SpamAssassin. Go to this site: http://www.globalshareware.com/.and download the software. I think it may pull you out of this trouble.
