[Exim] OT: SMTP-only servers

This is only kinda related to exim - does anyone know of a live server
that doesn't respond to EHLO? I want to test something but I don't know
of any servers that don't speak esmtp off the top of my head. I'd prefer
an actual installation I could bounce a couple of sessions off of, but
even types of servers would get me farther than I am...

Thanks
