Your next paragraph indicates that you are on the duhl.dnsbl.sorbs.net

not be sending direct to MX.

Hmm . . . . even addresses which, once allocated, might not change for weeks 
at a time? i'm on cable . . . .

Different DNSBLs have different policies. list.dsbl.org does not time
out, but delists on request. The sbl removes IPs based on the removal of
the spammer. Spamcop has a three day lifetime for its entries. Normal
entries from dnsbl.sorbs.net expire in three months, but never from the
duhl.

*nod* Okay, thanks.
