    hi, my outgoing e-mail works fine but when i sent to a client through sbc
    pacific bell, there spam software filters it out. using dnsreport.com i get
    this message:

    WARNING: One or more of your mailservers is claiming to be a host other than
    what it really is (the SMTP greeting should be a 3-digit code, followed by a
    space or a dash, then the host name). If your mailserver sends out E-mail
    using this domain in its EHLO or HELO, your E-mail might get blocked by
    anti-spam software. This is also a technical violation of RFC821 4.3 (and
    RFC2821 4.3.1). Note that the hostname given in the SMTP greeting should have
    an A record pointing back to the same server. Note that this one test may use
    a cached DNS record.

    server.XXXXXXXXX.com claims to be host XXXXXXXX.com [but that host is at
    XXX.XX.XXX.X (may be cached), not XXX.XX.XXX.X.

    i cant seem to find how to change this smtp greeting name. thanks.

    Hi Partner,


    Thank you for posting here.

    From your post, I understand you can not send email to a specific ISP (sbc
    pacific bell)

    Before we go any further, I would like to collect following info from you:
    1.Can you send a copy of NDR?
    2. Enable Diagnostics Logging on the Exchange 2003 server.
    a. Start Exchange System Manager.
    b. Expand "Servers", right-click "<Your_ Server_Name>", and then click
    "Properties".
    c. Click the "Diagnostics Logging" tab, and then click
    "MSExchangeTransport" under "Services".
    d. Under "Categories", select all options, and set the Logging Level to
    Maximum.
    e. Reproduce the problem, after the problem occurs, save the Application
    and System log files as .evt files and send them to me.
    f. Please let me know the problematic sender and recipient's email address.
    E-mail address:


    Since we can not narrow down the root cause, I suggest your contact the
    administrator of SBC Pacific Bell to ensure why blocking messages from your
    domain.

    In addition, from your report, I noticed you domain did not register PTR
    record, This problem may occurs when your outbound Internet mail server
    does not have the correct DNS configuration required to send mail to
    specific ISP. Some ISP's mail server requires that a valid reverse DNS
    record (known as PTR) for all of your domain's MX records. Maybe SBC
    Pacific Bell also requires that for every inbound SMTP connection, the
    connecting SMTP server must have a valid PTR record even if an MX record
    does not exist. Create a valid PTR record at your ISP. Or the work around
    for forward to host will resolve this as well.


    Hope this helps. I look forward to your update. If anything unclear, don't
    hesitate to let me know.


    Have a nice day!


    Best Regards,

    Chace Zhang (MSFT)

    Hi,


    Thanks for you update.

    How to save application log?

    After you enable Diagnostic logging and reproduce this issue ( I suggest
    you send email to problematic address for several times)
    Click Start, click Run, and then type cmd. At the command prompt type
    EVENTVWR, and then press ENTER.

    Highlight application and right click go to "Save log File as" save it as
    .evt files and send them to me.


    In addition, let's clarify your situation for further analysis:
    You mentioned "I sent to a client through sbc pacific bell"
    Is this client in your domain or belonging external domain? If it is a
    external recipients, can you tell me the destination domain?


    Please apply the steps I provided in the previous post.

    If you have any concerns or need more help, don't hesitant to let me know

    Have a nice weekend.

    Best Regards,

    Chace Zhang (MSFT)

    Chace,

    Wrong log. You asked him to "2. Enable Diagnostics Logging on the Exchange
    2003 server."

    Those logs would be the SMTP logs and/or the Exchange logs.

    Default locations for Exchange 2003:

    SMTP logs = C:\WINDOWS\system32\LogFiles\SMTPSVC1
    Exchange logs = C:\Program Files\Exchsrvr\MAIL.log

    ZIP them before sending! They can get quite large. They are plain text, so
    they compress a lot.

    Hi Gregg,

    Thanks for your info.


    I think enable diagnostic logging and SMTP logs are both useful to narrow
    down this issue. Thank you fill in the content.

    1. Enable Diagnostic Logging to determine the root of the transport issue.
    To enable Diagnostic Logging on the MSExchangeTransport service:

    1). Start Exchange System Manager.

    2). Navigate to the server object.

    3). Right-click <Server object>, and then click Properties.

    4). Click the Diagnostic Logging tab.

    5). Under Categories, click MSExchangeTransport.

    6). Under Logging Level, choose maximum for all the items. Restart the
    server.

    7). Let a user send an outbound message and copy all Exchange relative
    events in Event Viewer.

    For more information regarding how to troubleshoot Exchange problems,
    please refer to the following article:

    General troubleshooting for transport issues in Exchange 2000 Server and in
    Exchange Server 2003
    http://support.microsoft.com/?id=257265

    2. Enable SMTP logging and gather SMTP log to troubleshoot the issue:

    A. Open Exchange System Manager, expand Servers -> <Server name> ->
    Protocols -> SMTP, right-click "Default SMTP Virtual Server" and click
    Properties.

    B. Under the General tab, check the option "Enable Logging".

    C. With "W3C Extended Log File Format", click "Properties".

    D. Under "General Properties", make sure "Use local time for file naming
    and rollover" is CHECKED.

    E. Switch to the "Extended Properties", and then select to enable All the
    logging Options.

    F. Click OK to apply the modification.

    G. Right-click Default SMTP Virtual Server and click Stop.

    H. Right-click Default SMTP Virtual Server and click Start to restart the
    SMTP server.

    I. Reproduce the issue, repeat step G to stop Default SMTP Virtual Server,
    copy out or zip the SMTP log files in the
    "%systemroot%\system32\logfiles\SmtpSvc1" folder, and then restart the
    "Default SMTP Virtual Server".
