Usually this happens because the helo parameter sent by the MTA is just
"servername" instead of "servername.domain.com".  Also, ideally, this should
be the same data as found in your public PTR record.

The helo host can be changed by adding the parameter to
/var/qmail/control/helohost, although this is only needed if
/var/qmail/control/me is something weird.

Subject: [vchkpw] Helo command rejected?

Hi, my qmail installation is working fine, but when I try to send mails to
recipients of some domains (such as libero.it), the mail is bounced back
with this error:

Reporting-MTA: dns;myservername
Received-From-MTA: dns;myservername
Arrival-Date: Wed, 19 Oct 2005 12:59:48 +0200

Final-Recipient: rfc822;[EMAIL PROTECTED]
Action: failed
Status: 5.5.0
Diagnostic-Code: smtp;504 <myservername>: Helo command rejected: need
fully-qualified hostname

So, there's something I need to setup in qmail to avoid this response?
