Unless you have some strange log_selector settings, this means that the
remote end did one of the following:

HELO/EHLO -> disconnect
HELO/EHLO -> MAIL FROM -> disconnect

If you want to have all connections logged differently if they have
never received a MAIL FROM command, add +smtp_no_mail to your
log_selectors.

http://docs.exim.org/current/spec_html/ch49.html#SECTlogselector

Since that domain is listed on SURBL and they sending side couldn't
handle even a few seconds delay while you looked them up in a DNS
blacklist, I would say it's not a host worth worrying about.
