macOS email incorrectly associates name to email address
I use macOS email. There is someone I personally email, at either (for example) john@gmail.com or john@someplace.edu, who is also on a mailing_list@googlegroups.com. Every several months, when I start typing "john", I get the personal emails and a new recipient option of john_via_mailing_list, that happens to come first and be the default. So I have accidentally spammed the mailing list. I know how to ``remove address''. But why does this happen - I don't think I am doing anything to create it - and how can I stop the option from recreating itself in the future? It does not seem like any of the other recipients on the mailing list get associated with it.
