Email Policies to Block Incoming Domains

Email Policies to Block Incoming Domains

Under Mail Administration within my Control Panel I have an Email Policy with a Mail restriction type for incoming Domain emails.  I can add and block my work domain all day long however, most other domains where I receive spam are ignored.  For instance I receive a lot of spam from the following domains:

  • etungs.com
  • worldwidemidst.com
  • mremot.com
  • coroyo.com

Every one of these have been added as block incoming domain email policy and none of them work.  Again, I can add my work domain to this list and it will be blocked as expected.

What is going on?  I have read enough other forums from Zoho to know that many people are less than thrilled with the spam and blacklist abilities.  Is the lack of real solutions and issues like this our blaring sign to pay for a service elsewhere?
