Sorry, but nothing I tried works. I fired up my Power Mac 7500 to see what I had done many years ago. Back then I made a group in the Contacts Book into which I put email addresses of those senders I wanted to “block.” When an email was received from any of those senders, the email was downloaded and then promptly deleted. As for the Mail program, there seems to be no easy way to get sender addresses into a group or keep them out of the main listing even if I get them into a group. I tried using the VIP designation to isolate addresses, but no luck. I need an easy way to delete emails from specific senders without all those useless filters that are far more trouble than they are worth. If I upgrade the system software, 19 years of record keeping become inaccessible. Any more ideas?
