This article contains the best practices to minimize the amount of spam that you receive as a customer of Intermedia. Unfortunately, the tactics and methods that spam email senders use change every day, and inevitably some spam messages may get through. However, we continue to work hard to prevent as much as possible.

Protect your email address

  • Do not post on public forums.
  • Do not use your email address on online websites.
  • Never reply to spam messages, never click on links in spam messages, and don't try to remove yourself from the spam mailing list.
  • When subscribing to an email list, check to make sure the list owners have published policies regarding list management (how to subscribe, do they perform confirmed opt-in, how do they let you unsubscribe, will they sell your address to other lists, how do they handle bounce processing, etc). If they are not up to par on these standards, it is likely that they are running what would be considered a spam list.

Do not add your own domain to Safe Senders list in Outlook/OWA

Do not add your own email address or your domain name to Safe Senders or Safe Recipients in Outlook or OWA. This will cause a problem with our spam filtering services and allow spam messages to pass into your Inbox.

  • In Outlook, you can view the safe lists and other junk email settings by navigating to Tools (or File) > Options > Junk E-mail and selecting the tabs for Safe Senders or Blocked Senders.
  • In OWA, you can select Options > Junk E-Mail (or Options > Block and Allow) to adjust these settings.
    On the Outlook Safe Senders tab, do not select the checkboxes Automatically add people I e-mail to the Safe Senders List or Also trust e-mail from my Contacts.
