Cannot retrieve pop3 mail via pop3 connector to exchange

Hi.
i have set up sbs 2003 with sp1, and are trying to configure the pop3
connector for Exchange.
I have set up everything right as far as i know, but I cannot receive
incoming messages. Outgoing works just fine.
I get three error messages in the apps log:

Id: 1019. The message download process finished with one or more errors.

Id: The downloading process for mailbox %% was ended with one or more errors.

Id: An error occurred during a POP3 transaction to server %%. The error is 0
(The operation completed successfully.)

The following message is in the tracking log in Exchange:

SMTP: Message submitted to Advanced Queuing
SMTP: Started Message Submission to Advanced Queue
SMTP: Message Submitted to Categorizer

The emails doesnt get dstributed to the users, but i can see them in the
Mailboxes under Mailbox store on the server.

I have reset the password on my isp and on the server. Doesnt help.
I suspect it has to do with the pop3 connector setup, or possibly the
firewall.

Does anyone have a solution to this?

Help much appreciated.

 

Hi Bjorn,

Thanks for using the SBS newsgroup.

From your description, I understand the issue to be: users can not receive
incoming mails with POP3 connector. If I am off base, please let me know.

Please try below steps to try to resolve the issue:

I. Please turn off EDNS0 support in Windows Server 2003 to see if the
problem can be resolved.

To do this, follow these steps:

1. Start a command prompt.
2. Type dnscmd /Config /EnableEDnsProbes 0, and then press ENTER.

II. Please try to stop the default SMTP virtual server (Open Exchange
System Manager, Navigate to Servers\ServerName\Protocols\SMTP\Default SMTP
virtual server.) and then try to receive mails from the remote pop3 server.
Please check if you can receive those mails. That should be placed into the
%systemroot%\InetPub\mailroot\Pickup folder.

If you can not find mails here, that indicates the Pop3 connector has not
been configured properly. Or the remote server is not working fine.

A: To confirm the remote POP3 server is working fine, I would suggest you
to use Outlook Express to retrieve mail from it. Is there any issue?

Test OE on the client workstation

a. logon to one of the client workstations in the SBS network.
b. Bring up the Outlook Express
c. Set up the POP3 account for the remote POP3 server on the OE
d. Connect and try to retrieve and read emails.

Please let me know if mails could be downloaded by OE on this Windows XP
machine

B: If users can retrieve mail from the pop3 server, I would suggest
deleting this POP3 connector for this user mailbox and recreating it. How
about the result?

II. If you can find mails in Pickup folder, please specify a mailbox where
undeliverable POP3 e-mail is sent. By analyze the NDR, you can know which
rules is not configured properly.

The default setting is to deliver undeliverable POP3 e-mail to the
Administrator account. To verify this, please follow the steps below:

1. Click Start, point to All Programs, point to Microsoft Exchange and then
click System Manager.
2. Expand Connectors, right-click POP3 Connector Manager and click
Properties.
3. On the Troubleshooting tab, check to see if you set the Exchange mailbox
field in the Undeliverable POP3 Mail section.

You can find that mails in the mailbox you set there.

After verified the POP3 connector settings, please test to see if you can
receive mails.

Hope above information helps! I am happy to be assistance to you and look
forward to your reply!

Have a nice day!

Sincerely,

Jenny Wu
