554 5.1.0 Sender Denied

    Question

  • Hello all, I'm new to Edge Transport and Forefront. I have a particular sender that is getting blocked and cannot figure out how to allow this one sender through. The message tracking log reports "554 5.1.0 Sender denied". I have added the senders domain and sub-domain into "Configure Content Allow Lists" in ForeFront, but it is still being blocked. Is there some other list I need to populate to let the messages through. I verified the domain and sub-domains are in the Safe Senders lists in the users' Outlook clients as well, but it still doesn't come through. Thank you

  • Hello

    In E2010 server :--

    As you told you have exchange 2010 with Forefront. You can Install the Anti Spam on the E2010 server and configure it.

    Content Filter, IP block list providers, Recipient Filtering & Sender filtering

    => And updated the AntispamUpdates

    Enable-AntispamUpdates -Identity <SERVERNAME> -IPReputationUpdatesEnabled $True -MicrosoftUpdate RequestNotifyDownload -UpdateMode Automatic -SpamSignatureUpdatesEnabled $True

    => Restart the Transport service on E2K7 server

    But let me inform you that if it is Exchange 2010 SP1 then Inbuilt Antispam on E2010 will not update properly. For that you have to use Forefront server and you have to configure Antispam properly on it.

     

    => If you still facing the Issue then Please contact Forefront server support team.

    It will help you to fix the issue.

  • Hi,

    Please try below stpes:

    1. Open Exchange System Manager.
    2. Right Click on Message Delivery and select Properties.
    3. Browse to the Recipient Filter tab and uncheck Filter recipients who are not in the directory.

    Within Exchange System Manager, expand the following:
    Servers > "Your Server" > Protocols > SMTP

    Right click on Default SMTP Virtual Server and select Properties. Click Advanced within the General tab and then click on (All Unassigned).
    Uncheck both Apply Sender Filter and Apply Recipient Filter.

    Restart the SMTP service from the command line:
    net stop "Simple Mail Transfer Protocol (SMTP)"
    net start "Simple Mail Transfer Protocol (SMTP)"

  • I beg your pardon, Jidan, but... how disabling the sender and recipient filtering will help the OP ?

    See, doing what you suggested, the server will start generating NDRs since it will accept messages (spam too - if it slips through the filters) even if they're targeting non-existing recipients and this in turn will cause the generation of NDR messages bouncing back to whoever (even a fake/spoofed sender) was specified as the mail sender; the final effect won't be so good and, in case you aren't convinced, I think that reading this may shed some light.

    I do believe that it would be a better idea leaving sender and recipient filtering in place and spending some time to look at the logs to track and possibly solve the issue

    my 2 cents

  • Hi again, I neglected to mention that I'm on Exchange 2010 running an Edge server with Forefront Protection for Exchange 2010 on it. After further review what I'm trying to figure out now is with ForeFront for Exchange being installed and all its services being enabled, should I disable the Antispam filters that Edge has enabled by default?

  • Hi all

    Please check your "junk filter option" in your mail program (e.g. Microsoft Outlook). That was the solution for me with the error "554 5.1.0 Sender denied". I hope it helps.

    Best Regards
