POP3 Connector errors - 1019, 1023, 1036

Even though end users get their emails without any issues, but I am continuously getting the following 3 errors for the POP3 connector on the SBS 2003:

Source: POP3 Connector
Event ID: 1019
The message download process finished with one or more errors.

Source: POP3 Connector
Event ID: 1023
The downloading process for mailbox <account [pop.sample.com]> was ended with one or more errors.

Source: POP3 Connector
Event ID: 1036
An error occurred during a POP3 transaction to server <pop.sample.com [account]>. The error is 10054 (An existing connection was forcibly closed by the remote host. ).

Can anyone tell me how to solve this issue? Thanks.

You are not the only one who is facing this problem. For those servers using POP downloads and for which we are paid to monitor, we can see these errors regularly. Also, we had applied the POP patches. I am also in the line to know some answers for this problem.

I had the same problem. The problem is based on DNS and a timeout by
receiving email via pop3. Just write the IP address and DNS Name of your
ISP's mail server in the host file of your SBS2003 and your problem is
solved. I did it and haven't anymore error messages in my log file.

I think that you can safely ignore the message, since the only effect would be a bit of delay in mail delivery. I would also suggest to ditch POP3 in favor of SMTP.
