Are you sure? This is what the Juno postmaster has to say about this:

System Administrators: note that the Juno client does not provide
members with TCP/IP.  As a result, it is not possible for Juno
users to access Web sites through Juno or to select an alternate
SMTP server from which to send their mail.  Thus, mail which
contains an @juno.com "From:" line but which was routed through
non-Juno SMTP servers most likely did not actually originate from our
domain.
