Exchange 2007 send connector question

I'm running SBS 2008, Exchange 2007. My users have an email domain www.abc.com.  When I let the SBS wizard set up internet email send connector, it configures the send connector but my users cannot send email out using the wizard config. It just goes no where.

I can change the Internet send connector the wizard made to include the smart host of www.abc.com and include the authentication of one of the users. Then THAT user's (of course) email flows just fine but the others get authentication errors.  Just FYI it is a mix of Outlook 2003 and Outlook 2010 clients. The working one is a 2003 client.

What am I doing wrong?  Thanks in advance

before i start, if you want users to see a message, do not post an message immediately after you initially post your question. this will indirectly said some one has response to your question :)

you have a abc.com.

when you said you setup internet email send connector via sbs wizard, did it successfully?
(power shell command get-sendconnector | fl )

when users cannot send emails, do it means it stuck in the queue?
on firewall, do you allow port 25 on the server to externally?
http://www.msexchange.org/articles_tutorials/exchange-server-2007/management-administration/exchange-2007-message-queues.html

do your ISP allow you to run mail server? (some ISP do not allow)

the use of smart host - are forcing all your email to jump to this host before reaching internet. so i wont put www.abc.com as it is not a host to forward email

what authentication of one of the users do you change from to? ( i really dont understand what you try to say)


i really need more information because the question do not make much sense to me

THANK YOU!  You gave me VERY good ideas back that put several things together.  And thank you for the advice on posting.


The internet send connector wizard DID complete successfully, and the email DOES just get stuck sitting in a queue.

I am checking Port 25 today.

I actually put the www.abc.com SMTP server in the smarthost field with the username/password of one of the users. So it works for that user only. But I understand now the smarthost field is really only for the ISP relay service.

So if it just sits in a queue what do you think?

if the email stuck in queue, what is the message explain that action?

do a quick check, can the server "telnet <isp mail server> 25"  
this will confirm you are allow to send to the isp or not.

also check with ISP, do they allow port 25 open on their network or not (some of them dont, residential ISP plan dont, and etc reason)

check with ISP that do they has relay services or not.

if you get me a power shell command of get-sendconnector | fl

i probably can read whether it has been setup correctly or not.

No ISP port 25.

There is too much info in the output of that command and for security I can't put it out on the net. Is there something specific you can ask me?

i am at home atm so i rely on feeding information.


NO ISP port 25 means? ISP do not have port 25? ISP do not block port 25? or ISP do not have a relay services?

Telnet could not connect to port 25 for the ISP mail server.

Ok I will put it together and post it here. Give me a second.

if you cannot telnet to port 25 for ISP mail server, i believe your firewall has blocked that .. (try to do this on your workstation) or your ISP is blocking it.


again, your ISP mail server usually accept all emails from it's own users.


who is your ISP if you don mind i asking?

The other ones were for testing and they are disabled.

Is there any way around Exchange having port 25 blocked?

That just means my ISP won't let me use them as a smarthost right?  So how can I configure exchange to use the smail.lpl.com domain to send receive email to the mailboxes?

Just curious, where are you located?

How funny, my last name is Grenda and the Grenda bus lines down there are an offshoot of my family that emmigrated to Australia before world war II.  I know the IT manager for that company because I used to get their email at my domain www.grenda.com.

Thank you for your help, I think I can get it form here. I REALLY appreciate you staying with me on this.  I'm a generalist and these types of specific problems are the things that kill my time.
