Indeed. I have been trying a few days sending emails to gmail, and sometimes comes a complaint.
The reply from gmail says:

Please use the SMTP relay at your service provider instead.

The lack of domain when negotiating at SMTP level, well, seems a different problem.
But better to find out how to relay email with my DSL provider.
