RE: Mail being blocked by spamcop.net

Steven, I have found these suspicious events (Event ID 7004) in the
application log this morning. If you would comment about their possible
meaning, whether I still may have a problem concerning e-mail bein relayed
through my SBS, it would be appreciated! SBS1 is my SMall Business Server
2003 server name. As of now, I am still not on SpamCop.net's list.

Event Type: Error
Event Source: MSExchangeTransport
Event Category: SMTP Protocol
Event ID: 7004
Date: 5/21/2006

User: N/A
Computer: SBS1
Description:
This is an SMTP protocol error log for virtual server ID 1, connection #43.
The remote host "208.36.123.75", responded to the SMTP command "rcpt" with
"550 <>: No thank you rejected: Account Unavailable, Possible Forgery ". The
full command sent was "RCPT TO:<maloney@xxxxxxxxxxxxxxxx> ". This will
probably cause the connection to fail.

Hi Mark,

Thanks for posting here.

Based on current information, this issue seems caused by blacklist in
bl.spamcop.net, but I checked the following blacklist and your domain is
not blocked:

http://bl.spamcop.net

So I suggest you enable the SMTP logging and then send me the log file to
my mailbox at v-stezhu@xxxxxxxxxxxxxx

1. Open the properties page of the SMTP Vitual Server in Exchange System
Manager.

2. On the General tab, check the "Enable logging" box.

3. Click Properties, click the Advanced tab and check all the boxes on the
list.

4. Click OK twice.

5. Stop and restart the SMTP virtual server.

6. Let the users send emails. Wait till you see the messages sitting in the
"awaiting" queue.

7. Right click the queue and choose Find Messages. Do not type anything and
click Find Now.

8. Let me know the senders and recipients'' email addresses of the messages
(This is very important as the log file will be very large and I have to
use the email address to search in the file).

9. Force connection to have the messages sent out.

10. Stop the SMTP virtual server.

11. Go to the C:\WINDOWS\system32\LogFiles\SMTPSVC1 folder and send me the
latest two (if there are many) log files to my work address:
v-stezhu@xxxxxxxxxxxxxx

Please let me know the above information so that I can provide further
assistance on this issue. I am looking forward to your reply.

Have a nice day.

Best Regards,

Steven Zhu
