How spam e-mail is dealt with and how you can configure your anti-spam policies Print

  • 5

Unfortunately the net is floaded with e-mail spam these days. Spammers try to find new ways every day to bypass spam filters and get in your inbox to advertise their products. For these reasons our mail servers will scan e-mails on receival and check if it can be considered as spam or not. Letigilo.com uses several techniques and online hash databases to verify the incomming e-mail resulting in 98% of the spam being marked with a ****SPAM**** tag in the subject line and being moved it to the IMAP Spam folder.


The anti-spam process in steps:

  1. The mail server receives an e-mail from someone for your e-mail account
  2. The anti-spam filters on the server will check if the received e-mail qualifies as spam or not
  3. The e-mail receives a score on a scale of 1 to 10, how higher the score, how more likely it is spam! The score is a mathematical sum that adds up. Every spam filter will return their spam score which together make up the final score.
  4. If the score is higher than the score you have configured through the plesk spam filter, the e-mail will qualify and be marked as spam. Legitimate e-mails who are verified valid and not as spam go to your mail inbox folder.
  5. The spam e-mail is marked with ****SPAM**** in the subject line and is moved to the IMAP Spam folder
  6. Spam (in the spam folder) older than 30 days are deleted automatically every night by the server

  4. Check 'Switch on spam filtering'

  6. Set a score for 'The score that a message must receive to qualify as spam', a safe score is 7.00
  7. Leave 'Add the following text to the beginning of subject of each message recognized as spam' on '****SPAM****' if you want the spam to be moved your IMAP spam folder automatically.
  8. Leave 'Delete spam mail when it comes to mailbox' unchecked if you want your spam e-mail to go into your spam folder. If you don't want to use the spam folder and want to delete the spam e-mail immediately, check 'Delete spam mail when it comes to mailbox'
