Hi,
Thanks for your new information.
First of all, please make sure that you have installed the following fix:
835734 Many unexpected outbound e-mail messages appear in the SMTP queue in
Small Business Server 2003
http://support.microsoft.com/?id=835734
If this issue persists with this fix, the problem is generally caused
because the ISP "expand" that piece of e-mail. If you send one piece of
e-mail to "user1" and "user2" in the same To field, some ISP will keep that
as a single piece of e-mail, or some will expand that as two. If you use
telnet and connect to the ISP, you may see two piece of e-mail with the
exact same size.
When POP3 connector downloads the e-mails, it sees two e-mails because you
do have two. First e-mail contains user1 and user2, and second e-mail
contains user1 and user2 also. That''s why you see multiple e-mail
messages. To avoid the problem, check with the ISP and not expand the
e-mail, or switch to individual mailbox, or use SMTP instead.
I would suggest you perform the following tests:
1. Send an e-mail to A@xxxxxxxx & B@xxxxxxxx, use the following steps to
check the e-mail on the POP3 server.
A. Bring up a command console and issue the following commands
telnet
set local_echo
open <POP3 server Internet IP> 110 ;REM such as "open 157.60.71.8".
User <User name> ;REM such as "User A"
Pass <User Password>
Stat
B. You will then get the output in the format "+OK <e-mail number>
<Return command>". For example, if it is "+OK 3 375", it means you have 3
e-mails in the mailbox.
C. Issue LIST, then you will see every e-mail with corresponding size
information. Such as:
1 123
2 123
3 129
D. Do you see duplicated e-mails in account A?
2. Use POP3 connector to retrieve the e-mails from another POP3 server; do
you receive the duplicated e-mails?
3. If you use a POP3 application as Outlook Express to download the emails
from the POP3 server, does this issue occur?
For more information, please refer to the following article:
264249 Exchange Server Connector for POP3 Mailboxes deliver multiple copies
of messages
http://support.microsoft.com/?id=264249
Please check the above and then let me know the results. If anything is
unclear, please feel free to let me know. I look forward to hearing from
you.
Have a good day.
Best Regards,
Steven Zhu
