RE: cannot send emails to somebody@AOL .com

Hello Martin,

Thank you for posting in the SBS newsgroup.

Also, many thanks for Nicolas's input.

According to your description, I understand that you cannot send emails to
somebody@xxxxxxxx If I have misunderstood your concern, please don't
hesitate to let me know.

To narrow down this issue, please answer and perform the following
questions and steps:

1. Based on my research, the Numeric Code: 4.4.7 means:

Possible Cause: The message in the queue has expired. The sending server
tried to relay or deliver the message, but the action was not completed
before the message expiration time occurred. This NDR may also indicate
that a message header limit has been reached on a remote server or that
some other protocol timeout occurred during communication with the remote
server.

Troubleshooting: This code typically indicates an issue on the receiving
server. Verify the validity of the recipient address, and verify that the
receiving server is configured to receive messages correctly. You may have
to reduce the number of recipients in the header of the message for the
host that you are receiving this NDR from. If you re-send the message, it
is placed in the queue again. If the receiving server is on line, the
message is delivered.

2. I also have tried to telnet AOL by using the same command, I got the
same result. I think you can refer to the below steps to try again:

telnet mailin-01.mx.aol.com 25
220-rly-xk01.mx.aol.com ESMTP mail_relay_in-xk1.1; Thu, 28 Jul 2005
00:04:51 -0400
220-America Online (AOL) and its affiliated companies do not
220- authorize the use of its proprietary computers and computer
220- networks to accept, transmit, or distribute unsolicited bulk
220- e-mail sent from the internet. Effective immediately: AOL
220- may no longer accept connections from IP addresses which
220 have no reverse-DNS (PTR record) assigned.
helo mydomain.com
250 rly-xk01.mx.aol.com OK
mail from:<martin@xxxxxxxxxxxx>
250 OK
rcpt to:<someone@xxxxxxx>
250 OK
....

3. Based on my research, nowadays many mail servers on the Internet are
enabled to perform reverse DNS lookup to make sure the senders'' SMTP
domains do exist. This is used to prevent spam emails which use fake SMTP
addresses. As I know, AOL will also perform reverse DNS check and if your
SMTP domain name is not resolved to the public IP address which the MX
record is pointed to, your emails will be rejected. I suggest you contact
your ISP and see if your SMTP domain is publicly registered and if yes, see
if the MX record is correctly pointed to your SBS 2000 server or to your
ISP''s mail server
(thus you use POP3 Connector to download your incoming emails from the
ISP''s mail server).

If you already have a publicly registered domain name, such as
YourCompany.com, and the MX record is also correctly configured, you need
to make sure you are using YourCompany.com as your primary email domain
other than the local domain name, YourCompany.local. To check this, open
Exchange System Manager, go to Recipients\Recipient Policies, double click
to open the Default Policy, click the "E-Mail Addresses (Policy)" tab, and
then make sure the "@YourCompany.com" address is listed as the primary
address (appears in bold). If it is not there, click New, choose "SMTP
Address" and add it. Check the "This Exchange Organization ..." box when
you add the SMTP address. If it is there but not bolded, you can select it
and click the "Set as Primary" button.

4. Additionally, please configure a SMTP connector to deliver all the
outgoing messages to AOL using Smart Host, and then check if the issue can
be re-produced.

If the issue is not related to this situation, please help to collect the
SMTP logging using the following steps:

a. Open the properties page of the Default SMTP Virtual Server in Exchange
System Manager.

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

c. Click Properties, click the Extended Properties tab and check all the
boxes on the list.

d. Click OK twice.

e. Stop and restart the SMTP virtual server.

f. Ask a client to send two test emails entailed "Test Email To AOL #1(2)"
to an AOL recipient. Wait till you get the NDRs.

g. Stop the SMTP virtual server.

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

I am appreciated your time and cooperation. If anything is unclear, please
feel free to let me know. I am looking forward to hearing from you.
