Network Solutions blocking emails from Horizon....

Occasionally we receive a notice from a user that their emails are getting bounced or blocked.  In the case of Network Solutions, Inc. (NSI), they have a very strong spam filtering system so even the most innocuous email might get flagged or blocked as spam. Thus, this disconcerting message is returned to the sender:  

554 5.7.1 The message from (abc123@amazonses.com) with the subject of (Email Subject Line) matches a profile the Internet community may consider spam. Please revise your message before resending.

While the fix is relatively easy, it is unfortunate our users have to jump through these hoops so that they can communicate consistently. Nevertheless, here are the steps:

  1. Login to your Network Solutions webmail account
  2. Go to Configuration
  3. Go to Safe List/Block Administration
  4. Click Safe list and enter 3 separate entries for
    horizonwebref.com,
    horizonstaffscheduler.com
    amazonses.com
  5. You’ll need to repeat this for each email account you have with Network Solutions.
