Best practice in Raiser's Edge to track address opt outs is to track a Do Not Contact and Do Not Solicit but LO only passes the Send mail to? field.  Please allow for the passing of data from a check box of "No Physical Mail" to path to a specific solicit code so we can grant donors wishes to opt out and comply fully with the CAN-SPAM act.  Thank you for taking the time to consider this as new functionality!
