I have not changed VERP_CONFIRMATIONS yet, but I enabled smtp sending via dovecot sasl authorization
and the mail was handled, delivered, and the list state updated to having that new member.

The new member was one of the virtual mailbox users on the same server with postfix, mailman, dovecot
so there was not much chance of catjuggling-request behaving differently than a catjuggling post.

I'll try VERP_CONFIRMATIONS = Yes and send via sendgrid again to test that.
