What to do with SPAM tagged mails?

The SURFmailfilter takes a decision to tag a mail as SPAM or not (more info). You can decide what to do with SPAM tagged mails: nothing, store in folder or throw away.
  • Do nothing: easy, mails labeled with '***SPAM***' in the header will be stored in your inbox folder.
  • Store in a folder: create a mail filter rule which delivers mails labeled with '***SPAM***' in the header into a spam folder.
  • Throw away: create a mail filter rule which delivers mails labeled with '***SPAM***' in the header into the special folder /dev/null.

  • On the menu click Rules and select one submenu items, e.g. Senders to add a rule to always reject (black listing) or always accept (white listing) an e-mail address.
