Confirmed.  I setup Thunderbird and forced it to use basic authentication and I was able to send messages about via SMTP:

mailnews.smtp: Sending message

Thunderbird by default wanted to use OAuth2 to log in which brings up a separate webpage where you would log in with your username, password and presumably 2FA/MFA if you had that enabled.

So it would appear if we could set the From email address then AOL & Yahoo (and sendgrid) would work, but longer term it appears that OAuth2 would need to be implemented which would also allow GMail to be used again:
