Thanks for your reply and detailed information.
I am sorry if I didn't clarify my intension in last thread. First, I
original intension is to verify whether the issue happens to the mails
between internal users or the mails from internal users to Internet user.
Since if the issue only happens to the mails to external users, it may be
caused by external mail server when it is offline or busy. You can double
verify whether the external mail server has no response for the mail from
When the issue happens again, in the Exchange Server, please telnet the
destination mail server which you cannot send mail to by the following
1. Click Start, click Run, type telnet, and then click OK.
2. At the Microsoft Telnet command prompt, type open server_name 25, and
then press ENTER.
3. To verify that you are successfully connected to the SMTP Mail Service,
type helo domain.com, and then press ENTER.
4. Type mail from: <InternalUser@YourDomain.com>, and then press ENTER.
5. Type rcpt to: <User@DestinationDomain.com>, and then press ENTER.
6. Type "quit" (without the quotation marks), and then press ENTER two
times to close the connection to the server and leave the Telnet session
For more information about these 6 steps, please refer to the following
XFOR: Telnet to Port 25 of IMC to Test IMC Communication:
Please let me know the result and capture a screen shot if there is any
error during this process and send to me directly: email@example.com.
By the way, from the Event Log you provided, I noticed Event Error 7004 and
7010, I am not quite sure whether they are related to the original error.
For your information, you can try the instruction in the article below.

| Thanks, Lee
| This is happening when Internal users try to send email. As for a better
| idea of what we have here:
| Simple setup - one Exchange 2003 box. On the same physical server is
| IHateSpam, for spam blocking, and Panda Antivirus for Exchange. We
| have a Blackberry Enterprise Server installed, but not on the same
| server. 40 users of the Exchange server, all SMTP, all local (or
| blackberry - 7 users). No POP or IMAP users.
| Did as you asked, and will send off to you.
| Thanks again,
