AntiSpam

AntiSpam allows to trace, filter out and delete spam messages coming to your mailbox. The system doesn't delete messages recognized as spam. It only marks them as spam and delivers them in a regular way, which is why these messages also count against your summary traffic.

You can enable antispam protection:
- on the mail domain level
- on the mail resource level

 

To enable antispam for a maildomain:

  1. Go to the Mail Info menu and select the mail domain from the drop-down box.
  2. Click Go and you will see the mail service details of the chosen mail domain:
  3. On the page you will be taken to, add antispam either for all mailboxes of this mail domain or for all mail resources (box, forward, alias, responder).
  4. Clicking the antispam icon will let you configure antispam settings for mail resources.
  5. Click the Submit button at the bottom of the form.

 

To configure antispam protection for a mail resource:

  1. Click the e-mail address in the E-mail list on the Mail Controls page. The following page will appear:
  2. Check the AntiSpam box.
  3. Click the Submit button at the bottom of the form.
  4. On the Mail Controls page click the Antispam icon in the Resources included column:

     
  5. Fill up the Antispam preferences page that will show:
    • Spam check level determines how aggressively spam will be filtered. Antispam filters analyze each email message as it passes through the gateway email server and score it between 1 and 14. The larger the number the more likely it is considered to be spam:
      • Very Aggressive: guarantees almost anything delivered to your mailbox will be legitimate. However you will lose a lot of email (rejects messages that score over 2)
      • Aggressive: guarantees anything delivered to you will be legitimate. Still a fair chance of false positives (rejects messages that score over 4)
      • Normal: might block some mailing lists messages (rejects messages that score over 7)
      • Relaxed: accepts semi-legitimate bulk mail (rejects messages that score over 10)
      • Permissive: accepts almost everything (rejects messages that score over 14)

      The default value is usually 5, but this can be changed by the hosting system administrator.

    • Spam processing: By default it is set to Mark as spam, but you can change configuration.
    • White List - sender e-mail addresses to accept
    • Black List - sender e-mail addresses to reject

    Note: White and Black Lists have priority over the spam check level.
    * you can use masks using '*' and '?'. For example: *@domain.com, ?abc@domain.com, *.domain.com
    * e-mail addresses or masks should be separated by ',' or ';' or 'ENTER' or 'TAB' or 'SPACE'.

  6. Click the Submit button at the bottom of the form.

Looking to manage/avoid e-mail spam. I don't mind using blacklist and managing it myself, but can you help me look at the cost-benefit of anti-spam (assume this means whitelist and blacklist in addition to your 1-14 categories) and postini? What are the costs per month, etc? Thank you.
