SMTP helo/ehlo needs fully qualified hostname

Hello,

I have a windows 2003 standalone (not in a domain) webserver. Let's
call this machine "webserver".

The websites on this server often send mail. For this I use the
default SMTP service in IIS 6.0. However it seems that the helo/ehlo
statement are not in compliance with the suggestions in RFC 2821
therefor a lot of mail gets rejected by the receiving mail servers
with the following statement:

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

I have tried the registry changes as suggested in the following KB
article:
http://support.microsoft.com/default...-us;186142#kb5

However this does not work. I would like my SMTP server to use a FQDN
in it's helo/ehlo statement, "webserver.domain.com" for example. How
do I accomplish this ?

Any and all suggestions would be welcome.

Thank you for your time,
Joris Joosten

It's been a while, but I seem to recall there being a MasqueradeDomain
metabase variable in the LM\SmtpSvc tree that may apply. Grab a copy of
MetaEdit from Microsoft and take a look.
