    As you noticed, relaying is denied in your configuration ;P This attack is
    possible if relaying is enabled, and it allows multiple redirections
    trough protected or external networks, which shouldn't be allowed.
    
    For clearance - this problem IS PRESENT FOR SURE in 8.9.2, as well as DoS
    attack described in previous mail... If Sendmail developers don't believe
    me, I can post an exploit here, but iyt isn't really necessary, imho....
