POP3 Connector

I am running SBS2000 and using the POP3 connector for Exchange. Not all of
my email accounts set up at the ISP go to the Exchange server in the end,
some individuals never connect to the server and use Outlook Express only.
However when someone connected to the Exchange server send an email to
someone within the company that is not connected to the Exchange Server they
receive an delivery failure notice from the Exchange server that that email
account doesn't exist. It is as if the Exchange sever never sends the email
past itself to the external mail server at the isp.

George,

One solution would be to move all users to being Exchange Server service
MAPI clients.

Is it possible that your internal domain name is the same as the public
domian name?
Is one .local and one .com?
If so, you may need to create DNS hosts records locally so that the
Internet E-mail clients can locate the
POP_SERVER and SMTP_SERVER at the external mail host.
Do the Internet E-mail clients have Exchange Server Service installed in
there profiles?
Do they all have maiboxes on Exchange?

Hi George,

You will have to forward all unresolved mailaccounts back to your ISP.
Quoted from previous post of Chad:

Open Exchange System Manager, and navigate to Servers | <servername> |
Protocols
| SMTP. Right-click on Default SMTP Virtual Server & select Properties. On
the Messages tab, enter your ISP's outbound mail server in the 'Forward all
mail with unresolved recipients to...' field.

Now, how does this work? In your example, you send an email to
home@proanalysts.com - Exchange isn't able to find a local account with that
address (and it thinks it is handling all mail for proanalysts.com). It now
forwards this message to your ISP's mailserver that you defined in the
Default SMTP Virtual Server settings. Your ISP recognizes that address as a
valid address and delivers it to the mailbox.

Marina,
Will this only apply to undeliverable messages sent to
mydomain.com? For example, if an employee sends an email
to jdoe@aol.com but the recipient does not exit, will the
sender still receive an NDR?

Thanks,
Don

Hi Don,

I'm guessing that your ISP would send the NDR, if the ISP is sending NDR's
(some of them don't).
