That's just the first level of protection. It IS possible, however, that a virus might randomly select another list member's address when it forges the "From" field and get past the restricted posting (although I have yet to see this happen). If this does happen, be sure to have the maximum message size set as low as you feel comfortable with, lower than the size of any virus. If someone invents a virus in the future which is very small in size and can also get past that, install DeMime. DeMime will strip any virus that gets that far.
