AntiSpam Protection

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.

2. Click to add antispam resource for all mailboxes or for all mail resources (box, forward, alias, responder) in this account.
3. You can delete all antispams in this account by clicking the Trash icon.

• 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 (processes messages that score over 2)
  • Aggressive: guarantees anything delivered to you will be legitimate. Still a fair chance of false positives (processes messages that score over 4)
  • Normal: might block some mailing lists messages (processes messages that score over 7)
  • Relaxed: accepts semi-legitimate bulk mail (processes messages that score over 10)
  • Permissive: accepts almost everything (processes messages that score over 14)

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

• Spam processing:
  Mark as spam: this will tag the email as spam, i.e. add the word SPAM to the subject line of the email and then forward the email on to the client as an attachment with details.
  Remove: this will delete the spam email so when the client performs a send/recieve, they will never see the email.
  Move To: this allows you to specify a mailbox spam email goes to. The client will never see this email unless they access the specified mailbox.
• MaxScore level ( in 2.4.3 RC 1), if not Undefined, overrides the Spam check level with an alternative score range from 20 to 500:
  • Very Aggressive - 20
  • Aggressive - 40
  • Strict - 60
  • Moderate - 80
  • Neutral - 100
  • Soft - 150
  • Permissive - 200
  • Loose - 300
  • Very Loose - 500

  If a spam mail is detected on this level, it is deleted irrespective of your choice for Spam processing.

• 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'.
