Hi,

what is the problem with putting a single computer into a hosting center, name it mycompany.com,
and also let it helo as mycompany.com?
Of course it should have reasonable dns entries but that's a different story

It's not considered an FQDN, it's a domain. Depending on how strict the helo syntax test is it will 
fail at this stage.
