Hello all, Hopefully a simple question and a simple resolution that you can assist with: Is there a way to block e-mails to Distribution Lists (exchange 2003) from a specific sender? Here is the reason - our spam filtering software sends out alerts to e-mail addresses once per week that shows what has been quarantined as spam so that the owner of the e-mail address can check for false positives. As you can imagine, it is not a good thing to have blasted to the e-mail address of a DL. Especially DL's that have external members... Any assistance or tips are greatly appreciated. Regards, Chris
