To create an email filter:

1. If you are currently forwarding your email to another server, you must first disable forwarding to use the Central Email filter service.
2. Log into Email Filter service.
3. Select Create a new filter. Click Continue.
4. Select one of the following filtering options:
   • Filter Message Headers
     Type filter terms into the following fields: From, To, Subject, Cc, Date, Other. If all the fields are left blank (unless the filter is positioned directly before a filter that contradicts it), all incoming messages will be forwarded, deleted or filed.
   • Filter Potentially Executable Attachments
     Match messages with attachments that have one of the following extensions: exe, com, bat, pif, cmd, scr, vbs, js, jse, wsf, wsh, lnk, dll, or ocx.
   • Filter Non-Western Character Sets
     Match messages that are not written in any one of the following character sets:
     English (US-ASCII), Western (ISO-8859-1, ISO-8859-15, IBM-850, MacRoman, Windows-1252), or Unicode (UTF-7, UTF-8).
5. If you select:
   • File: Select an existing folder from the pull-down menu or create a new folder by entering a name for it
   • Forward: Enter the email address to which you would like to direct the filtered email.
   • Delete: Take no action.
6. If a message matches a rule, you can either stop performing any additional filter rules on that message or continue on to the next rule using that same message.
7. Select Enable advanced options to continue applying other rules to the message after it matches a rule. Select Continue to see if other rules match.
8. Click Create to finish creating the filter.
   
   

SPAM filtering is available through the Advanced Options button at the top of the filter page:

• Filter Based on SPAM Rating: The default setting is 50% or greater likelihood of being SPAM. Be warned that if this number is set below 50, there is an increased chance that legitimate email messages may be misidentified as SPAM.
  
• Filter Mail with a Bulk Precedence Header: This will filter out messages with a precedence: bulk header. Many legitimate mailing lists also have this header.
• Filter Mail Based on DCC Rating: Filters based on the DCC rating. Many is the default. 5000 and 500 are other options. The lower the number, the greater the risk of misidentifying legitimate email as SPAM.

2. Select the rule from the list of existing mail filters.

4. Click Continue.
