I saw a post on this subject already, but the last part of it was never repl
ied to, so here it is again, in hopes of recieving an answer.

Is the Microsoft IIS 5/6 SMTP Server RFC1123 5.2.17 compliant? In case you a
re unsure, this RFC compliance deals with Domain Literals.

When using http://www.dnsreport.com to test my DNS/Email/Web workings, I rec
ieve a warning from our backup MX stating that it does not accept domain lit
erals.

WARN: One or more of your mailservers does not accept mail in the domain lit
eral format (user@[0.0.0.0]). Mailservers are technically required RFC11
23 5.2.17 to accept mail to domain literals for any of its IP addresses. Not
 accepting domain literals can
make it more difficult to test your mailserver, and can prevent you from rec
eiving E-mail from people reporting problems with your mailserver. However, 
it is unlikely that any problems will occur if the domain literals are not a
ccepted.

smtp.intraforce.com's postmaster@[xx.xx.xx.xx] response:[vbcol=seagreen] 
<<< 550 5.7.1 Unable to relay for postmaster@[xx.xx.xx.xx]

Please advice.

As far as I know, the IIS mail server doesn't claim to be compliant with
that part of RFC1123.  For what it's worth, Exchange Server isn't compliant
either.  In practical terms, this non-compliance isn't an issue -- no one
really uses domain literals.

Actually, Exchange Server IS compliant with the right configuration. You jus
t have to add the "@[xx.xx.xx.xx]" into a Recipient Policy, and add your
 addresses as "Custom" with the address of "postmaster@[xx.xx.xx.xx]" or
 "abuse@[xx.xx.xx.xx]" and type SMT
P (choosing SMTP and trying to add the address WON'T work).

I like to have ZERO warnings or errors in my testing though, so if ANYONE ca
n give me the answer on how to do this, or if it is simply NOT possible that
 would be great. If it is truely NOT possible, I would like it to be a MS re
p that breaks that news to
me, thanks.

Is the Microsoft IIS 5/6 SMTP Server RFC1123 5.2.17 compliant?

Yes it is, just create a domain name [xx.xx.xx.xx] with adsutil.vbs, you
can find this script in c:\inetpub\adminscripts

start the following commands:

adsutil create smtpsvc/1/Domain/[tcp/ip] "IIsSmtpDomain"
adsutil set smtpsvc/1/Domain/[tcp/ip]/RouteAction 4098
adsutil set smtpsvc/1/Domain/[tcp/ip]/RouteActionString ""
adsutil set smtpsvc/1/Domain/[tcp/ip]/RouteUserName ""
adsutil set smtpsvc/1/Domain/[tcp/ip]/RoutePassword ""
adsutil set smtpsvc/1/Domain/[tcp/ip]/AuthTurnList ""

That's it...

Harland Adelaars.
