Hello,

Outlook Error:::

I occasionally get the following error message, usually when attempting to
forward an email.

"504 <BUILDUP23>: Helo command rejected: need fully-qualified hostname"

Does anybody know what drives this error and what I can do to fix it? This
is not a big problem, just an annoyance, but would like to eliminate it.

Thank You
Fred

This is caused by an SMTP client sending its HELO or EHLO command to the
SMTP server and not including a fully-qualified domain name as the
parameter. For example, a proper HELO command, in this case might be:

HELO buildup23.mydomain.com

What the server is seeing instead is

HELO buildup23

This should be controllable by the networking settings on your PC. You have
your TCP/IP settings such that your PC has no domain name and some SMTP
servers don't like that. The solution is to configure your TCP/IP such that
when you are connected, the domain of the ISP is appended to your PC name so
that it's fully-qualified.

Hello Brian
Thanks for your response. I am sorry, but I am not a Computer expert; not
even close. Can you guide me to where I check for this setting? I went to
<settings> <network connections>, but I can not find anything related to
TCP/IP.
Thank You
Fred

I'll respond as soon as I check something at home.

Open your Network Connections applet in Control Panel (or right-click My
Network Places and choose Properties) and right-click the network
connection, choosing Properties. The TCP/IP protocol will be in slide list
at the bottom. Select it and choose Properties. Click Advanced and click
the DNS tab. Add the proper domain suffix in the "DNS suffic for this
connection" box.
