Anti-Spam Email Information - Linux

Understanding and FILTERING SPAM using cPanel


Linux accounts come with SPAM ASSASSIN - Our default setting is to send messages marked as high probability of being spam to your online Junk Email box.  We don't want you to loose legit email so we have implemented the following options so that you may enjoy the benefits of the anti-spam service and reduce the chance any legit email being caught.



  1. You can easily whitelist important email addresses so they are not check for spam
  2. Conversely, you can further 'tighten' the spam restrictions to your preference.
  3. You can completely disable the anti-spam options.


General Notes:

Messages between users of the same domain are generally NOT filtered. However, if you are not sending mail through our mail servers then it is recommended you whitelist internal users. Our Anti-Virus Protection is still in effect and we also have some Banned File Extensions (KB on Banned Extensions). We do not allow EXE's or password protected (EZIP) files to be sent by email. Senders will be notified with a way to send such files by email safely. Finally, Messages in your Junk Email folder will be auto-cleaned when they reach 10MB. The oldest messages will be removed until the folder is at or under 2MB. Depending on the size of the messages being sent this is about 300-500+ message.
