I am having the same issue. I have 3 AOL Verizon email addresses. It only has let me add one of those addresses to my mailhosts. When I get spam from an address that SC doesn't take it says it can't do anything since that mailhost isn't listed for my account here. I used to be able to report all of my addresses now I'm limited to just one for AOL Verizon, one for Gmail, when I have 3 email addresses for each of these. I keep trying to add them back but it won't send a test email to anything else after I've set up one address. Has something changed here?
Appreciate any help I can get!
