Reducing Spam

Content Filters

To reduce the amount of spam you receive, add a Content Filter named "URIBL_BLACK" (no quotes) and then set it to move any email with URIBL_BLACK in the HEADER to the JunkMail folder.

Also, create another Content Filter just like the one above except name it "RCVD_IN_PBL" (no quotes) and have it move any email with RCVD_IN_PBL in the HEADER to the JunkMail folder.

There are many blacklists, but these two seem to be very reliable.

The following is how to add a content filter to your domain to reduce spam by filtering out e-mails marked by our server level spam filters and blacklist lookups:

• Login at http://mail.yourdomain.com/ with the mailadmin@yourdomain.com e-mail administrator.

(Replace yourdomain.com with your actual domain name)

1. From the 'Domain Settings' drop-down menu, select 'Domain Content Filtering'
2. Click on the 'Add Filter' icon
3. Under the 'Contains Specific Words or Phrases' group, check 'Email Headers'
4. Click 'Next'
5. Under 'Filter Type', choose 'OR'
6. In the large text box, enter the following four lines:

URIBL_BLACK
RCVD_IN_PBL
Bayesian

1. Click 'Next'
2. In the text box labeled 'Rule Name', enter "SA BL Content Filter"(without the quotes)
3. Under the 'Actions' section, Check 'Move message to folder' and enter "Junk E-Mail"(without the quotes) into the text box
4. Click the 'Save' icon

• You should notice a nice reduction in the amount of spam to your inbox after creating this filter.

• You'll want to occasionally check the 'Junk E-Mail' folder from time to time to make sure nothing is getting caught that you don't want caught or if you think you are missing an e-mail.
