  • SPF records and Exchange 2003

    Hi,

    I am running Exchange 2003 SP2,
    Anyone knows if there is an option to enfroce SPF records in exchange (and mark as spam everything that doesnt match the sender's domain SPF record) ?

    What I am looking for, ofcourse, is for an option to do it without having to pay for additional software.

    Thank you,
    Ido.

    Sure. Global Settings > Properties. You'll see a Sender ID tab.

    Pay attention, Exchange has "some challenges" with SPF.

      Daniel missed out part of the settings, it is in Global Settings, Message Delivery properties where it is enabled by default for accepting the message.
      You also need to enable it on the SMTP virtual server.
      ESM, Servers, <your server>, Protocols, SMTP. Right click on the Default SMTP VS and choose Properties. Click on the Advanced button, then edit. Enable the filter. Apply/OK out and restart the SMTP virtual server.

      My personal opinion is that SPF, much like Sender ID and similar schemes are a waste of time. The take up of those ideas is too low to use them for anything more than scoring.

      Don't set the server to block messages that fail the SPF record as you will block the majority of your email unless you do not deal with any small sites.
