[SOLVED] missing documentation: helotests

[Elompenta]

Hi together,
is there some more documentation to explain the configurations "SMTP HELO checks" in Configuration :: Mail Proxy :: Options ?

In the docu is written:

helotests: <boolean> (default = 0)
Use SMTP HELO tests.

I not really understand what these configurations do in detail.

Should be this one http://www.postfix.org/postconf.5.html#smtpd_helo_required

Can someone give information about how blocked messages would look like if this setting is enabled? How is it shown in the logs if message is blocked with this setting?

EDIT:
looks like it's this
Helo command rejected: need fully-qualified hostname;
