RBL Status is, so far, the only Multi-DNSBL checker app for iPhone and iPad — using RBL Status you can quickly check a list of your hosts against multiple DNS blacklists.
RBL Status checks your hosts against multiple DNS blackhole lists and present the information in a convenient way. With RBL Status you can quickly and easily determine which RBLs are currently listing hosts from your monitoring list.
DNSBL lookups are performed using asynchronous algorithms that allow RBL Status to operate quite fast — a lot of lists are checked within very short time.
