    SORBS doesen't send messages. Your thinking of ORBS which probes
    submitted mailservers to detect relaying. SORBS is like most
    other blacklists in that it uses spamtraps.

    The solution is for SORBS to determine which ones of their spamtrap
    e-mail addresses is being forged, then replace them with different
    spamtraps.
