Re: POP3 Connector hiding mail

Hi again!
I have tried to do the setup and to trigger the settings for the server
multiple times by now, but every time, it all just comes down to one single
Warning message in the log: The message could not be routed due to that the
recipient's email domain does not match any local email domains. I have set
up the email domain (as I am in Sweden). When the user then
presented me with the fact that she wanted to have her email address
downloaded to the server, I thought that it would be just ok, but no, it
wasn't. The adress that I am using in the POP3-connector is like
user1@xxxxxxxxxxxxxxx Since the is not in the server, I do not
know how to get past this error message in the POP3 Log. I figure that this
could be a reason to why email messages get fully downloaded from the
POP3-server at the ISP but not routed to the correct Exchange account.

When trying to use the advice that Merv Porter [SBS-MVP] supplied, I checked
the Microsoft help in troubleshooting the POP3 connector. Disabling the SMTP
virtual server in the SBS did show me that the messages were downloaded
properly, as they were lying in the %PROGRAMFILES%\Microsoft Windows Small
Business Server\Networking\POP3\Incoming mail folder. I hence now know that
the messages are encountering trouble when they are routed to the server's
individual Exchange mailboxes.

Does anyone know of a solution to incorporating the ISP email domain into
the SBS configuration, such that the error message from below does not keep

Event Type: Warning
Event Source: POP3 Connector
Event Category: Delivery
Event ID: 1070
Date: 2008-12-04
Time: 15:24:04
User: N/A
Computer: <Servername>
An attempt to relay e-mail to recipient <recipient's email address at ISP>
was made. The e-mail could not be delivered because the recipient's e-mail
domain name does not match any local e-mail domains.

I'm a little confused by your setup for User1. Your setup appears to be the
standard way that POP3 Connector is set up yet you say that User1 needs to
retrieve mail "on demand". I'm also not sure what you mean by "a mapped
user mailbox".

In any event, check the following locations to see if the mail landed here:

C:\Program Files\Microsoft Windows Small Business
Server\Networking\POP3\Incoming Mail
C:\Program Files\Microsoft Windows Small Business
Server\Networking\POP3\Failed Mail

Also, makes ure that your antivirus software software on the server is not
scanning (either realtime or scheduled scan) the Exchange folder:
C:\Program Files\Exchsrvr

I am having an issue with a POP3 Connector within an SBS2003 (non R2)
The server is running for two users - user1 and user2. User2 uses POP3 for
email retrieval only and then synchronises the emails into the user's
Exchange store for backup purposes. This functionality is perfectly well

As for user1, there is a somewhat different situation. Here, since the SBS
POP3 Connector has a minimum retrieval interval ofo 15 minutes, user1
to be able to retrieve emails on demand. Hence, the setup has been made as
follows for user1:

POP3 Connector connects to the POP3 account at the ISP and retrieves any
emails that are stored there, then deletes them from the POP3-account at
ISP. The Message Delivery component of the POP3 Connector then routes the
messages to a mapped user mailbox. The user mailbox chosen in the POP3
Connector is identical to the user alias of user1. Nevertheless, the
retrieved with the POP3 Connector disappears.

When manually executing an email retrieval from the POP3 Connector
Properties, logging is set to maximum, and in Application log, the
seems to have exited properly.

After such a finished retrieval, the emails are not left at the ISP,
do they show up in the specified user's mailbox, nor in the

Does anyone have any clue about what that is happening here? All updates
have been installed on the server.
