HORDE: how to modify E-MAIL SPAM FILTER

Except for some “ old ” users, all the incoming mail tagged as [Maybe SPAM] are automatically moved in the folder INBOX_spam (depending on your spam level value).
The users who use POP can access to INBOX_spam folder using webmail service (horde) ONLY.

Each incoming mail is scanned by our anti-spam filter, that assigns it a SPAM-SCORE VALUE.
If an e-mail is suspect, the anti-spam program tags it as [Maybe SPAM] and assigns to it a SPAM-SCORE VALUE starting from 3.5.
Depending on your Spam level set using horde (default 5), the incoming mails will be delivered into the INBOX or INBOX_spam folder.
For example using default settings:

• an e-mail with value 5 (and tagged as [Maybe SPAM] because its value is > of 3.4), will be delivered into the INBOX_spam folder;
• an e-mail with value 4 will be delivered into the INBOX folder, but tagged as [Maybe SPAM] because its value is > of 3.4;
• an e-mail with value 3, will be delivered into the INBOX folder.
  

If you set 1 as your Spam level a lot of your incoming mails will be delivered into the INBOX_spam folder (LICIT E-MAILS TOO!!!!).
If you set 9 as your Spam level a lot of your incoming mail will be delivered into the INBOX folder (SPAM MAILS TOO).
So if you wish to change your spam level, choose carefully.

You have to check and empty the content of the INBOX_spam folder from time to time.
