I do this as well -- rblcheck is a great utility for this.  However,
not all blocks are done via public DNSBL's.  There are ISPs that have
their own internal lists and such, and the only way to find them is to
*manually* inspect your mail servers' logs to look for the random
verbage they chose to let you know they're blocking you, or wait until
you get complaints from the ones that drop your messages silently.
