Blocked by port blocking rule (Anti-virus Standard Protection:Prevent mass mailing worms from sending mail).

We have a program that uses CDO to send mail.  It worked until we upgraded our McAfee to 8.7.0i.  The mail is now blocked.  The McAfee event viewer message is Blocked by port blocking rule (Anti-virus Standard Protection:Prevent mass mailing worms from sending mail).  The vbs error is The transport failed to connect to the server. (code 80040213)

How can we set up an exception in McAfee to allow this to work?  Our network administrator is telling us that we need to identifiy an EXE to add to the exception list.

    In McAfee you can check the log file and it should tell you which program is getting blocked by that rule.

    You need to enter that program name (don't need the path) into the exception list.

    Open the McAfee console and It's the top item - Access Protection Policies (I think that is the name).

    You can also change the rule to just Notify (uncheck the Block checkmark) or disable the blocking if needed.

    We went into the Rule Details of "Prevent mass mailing worms from sending mail" and added MSACCESS.EXE to the "Processes to exclude".
