Need to blacklist (block) a large number of domains and email addresses

Question

I tried to import a large number of domains into a transport rule (new/set-transportrule -name xxx -domainis $csv -quarantine $true). 
I added a few domains manually and tested to make sure the rule was working.  It was.  Then I ran the cmdlet to import a small number of domains (4).  That also worked.  Then I ran the cmdlet on a large number of domains.  The cmdlet
worked with no error message (once I got the list of domains well under 4096 bytes).  I waited a day to see if the domains would show up in the rule.  But the imported domains did not show up.
Is there a better solution to blocking large numbers of domains and email addresses?  Or is the transport rule the only option?

Since you do not want to crop your images to a square 1:1 aspect ratio changing the canvas to be square will not make your images square they will retain their Aspect Ratio and  image size will be changer to fit within your 1020 px square. There will be a border or borders on a side or two borders on opposite sides.   You do not need a script because Photoshop ships with a Plug-in script to be used in Actions.   What is good about Plugins is the support Actions.  When you record the action the plug-in during action recording records the setting you use in its dialog into  the actions step.  When the Action is played the Plug-in use the recorded setting an bypasses displaying its dialog. So the Action can be Batch.  The Action you would record would have two  Steps.   Step 1  menu File>Automate>Fit Image... in the Fit Image dialog enter 1020 in the width and height  fields.  Step 2 Canvas size enter 1020 pixels in width and height  not relative leave the anchor point centered it you want even borders on two sides set color to white in the canvas size dialog. You can batch the action.
The above script will also work. Its squares the document then re-sizes to 1020x1020  the action re-sizes the image to fit with in an area 1020 x 1020 then add any missing canvas. The script like the action only process one image so it would also need to be batched. Record the script into and action and batch the action. As the author wrote. The script re size canvas did not specify an anchor point so the default center anchor point is uses  like the action canvas will be added to two sides.
