Beats me, test it. Multi-HELO appears to be rather abnormal
if I got Ralf's drift. The last accepted HELO could be still
"the" HELO.
I'm surprised to discover that it can. I'd always imagined that
such a fail would return the client to the state where they
had to HELO first, but ...

It won't surprise me if different servers have
their own ideas about multi-HELO.
Yes, I'd be surprised if they didn't.
