Using your administration log in you can set email filtering at either the domain level or individual account level.
Log into your Administration zone and click on the Account Level Filtering or User Level Filtering icons in the Email section depending on which kind of filtering you wish to do:
Alternately, for individual account filtering, use this link and log in with your email account information.
On resulting page, same for either selection, click on “Create A New Filter”:
Step 1: Create Name for your Filter. Enter in the Filter name box.
Step 2: Create your Rule/s. Select your first and secondary conditions. Click on the “+” to the right to add additional conditions to the rule. Be careful, if you make the conditions too general you may block emails that you actually wish to receive.
Step 3: Specify the action to be taken. This is the action that the server will take on your email that has been filtered based upon the conditions (rules) that you selected above. Again, be careful, if you choose to Discard Message, it is gone forever. It would be advisable to chose to send it to other folder, “SPAM FOLDER” for a week or two and give yourself time to review how your filter is working before you change it to Discard Messages.
Step 4: Apply your filter. Click on the “Create” button at the bottom. You can then click, “Back” if you wish and test some emails to see how your filter will or will not accept them.
Again, this process is the same regardless of which filtering you choose, account or individual. Just remember, if you apply a filter for account, this will affect all email accounts in your domain/s.
