Wrong "from" e-mail address in replies, only sometimes
I have an old AOL e-mail that I do NOT want to remove from my account, because some things that I'm signed up to will only use that account, & I can't change it. I wish I could... anyway, I use my .me account for everything else. Sometimes, when I'm replying to an e-mail that has been sent to my .me account, the "from" field will default to my AOL e-mail. I have the settings correct already: mail > settings > composing > send new messages from is set to my .me address. Furthermore, a reply to an e-mail that has been sent to my .me address isn't really a "new" e-mail; it should *always* send from the address the original e-mail was sent to. Help! This has been happening for quite a while. I'm upgraded to Ventura, but that isn't an option when it asks about which macOS I'm using.
