important messages going into junk mail

Important messages from my attorney, her paralegal and my accountant keep going into junk mail. I created a rule for these email addresses according to AppleCare support. They are still going into junk mail. I just turned off the junk mail filtering about 20 minutes ago. Some other message was sent to junk. I am running Sequoia 15.7.2 on a Mac Mini 2025. This is happening in my Comcast email account. Anyone else having this problem? Is so, how did you solve it?
