Well, in our main log at the moment (9 hours after rotation) I see 46
entries containing
    H=fqdn (oemcomputer) [ipaddr]  P = smtp
where the name and the ipaddr match (naturally) and the (oemcomputer) seems
to imply that we got
HELO oemcomputer
(the P=smtp implies the HELO).  Old (Windows) machines, I'd guess.


Also, there seem to be a bunch of
HELO computer
some
HELO mycomputer
and I notice one
HELO susanscomputer

All "old" on the basis of HELO rather than EHLO.
