Re: Emails stuck in queue error 451 4.4.0 Primary target IP addres

Ed,
OK I get it I missed off the trailig port 25 in the Telnet command, couldn't
you have just said that and saved us both a heap of time. I am not familiar
with Telnet commands so it was not obvious to me what you were getting at?

OK so with the new knowlege we get this:

Microsoft Windows [Version 6.0.6002]
Copyright (c) 2006 Microsoft Corporation. All rights reserved.

C:\Users\Siv>telnet smtp.surfdsl.net 25
Connecting To smtp.surfdsl.net...Could not open connection to the host, on
port
25: Connect failed

C:\Users\Siv>

So I can no longer go any further I assume.

Ed,

Well if you look in my post I posted the command prompt and the reposnse I
get back, IE:

C:\Users\Siv>telnet smtp.surfdsl.net
Connecting To smtp.surfdsl.net...Could not open connection to the
host,
on
port
23: Connect failed

In other words at the command prompt I typed

telnet smtp.surfdsl.net

I am assuming the angle brackets are not part of the command as in your
text
before that you say:

<smrthost> is the name or IP address of your smarthost exactly as
you
have
configured it in Exchange):

In exchange I have "smtp.surfdsl.net".

When I type that and press return I get the following response back:

Connecting To smtp.surfdsl.net...Could not open connection to the host, on
port
23: Connect failed

So after that error I gave up.

Can you be more specific about what I am doing wrong as I am now very
confused by your replies.

Ed,
I did and it gave a rejection so I didn't proceed any further as I
assumed
the following stuff was dependent on the telnet login being accepted??

On your SBS server open a command window and type the following

(You should see a banner from the smarthost.)

This is a test.

Just before the quit, there's a period on a line by itself.

Post back with what happens. It'd be best to just copy the entire

to the clipboard and paste it in your reply.

Hi,
I am running Windows SBS 2008 Server.

I am trying to set our outbound email to use a smarthost
"smtp.surfdsl.net"
whenever I set up the SBS to use this smarthost mails start to
pile
up
and
if
I look at the oubound queues I can see an error alongside the
outbound
comnnector which says:

451 4.4.0 Primary target IP address responded with: "421 4.2.1
Unable
to
connect." Attempted failover to alternate host ..."

I cannot see why the "unable to connect" message is coming up? I
have
checked the router's firewall settings and all outbound TCP and
UDP
is
allowed.

Inbound port 25 is port forwarded to the server's internal IP
Address.

I have no Windows firewall rules that I can see that would be
blocking
this
(all outbound TCP and UDP is allowed and I can see no relevant
exception
rules that would impede SMTP outbound).

Can anyone suggest why this is happening. For the time being I
have
had
to
set the mail to direct delivery via DNS.

Any help appreciated.
