Specifically, both of the two large providers I've noted giving
problems consistently drop the connection without giving a response
for the BDAT LAST.o

Google is fine with a QUIT pipelined after data-ending-in-dot
(tranditional non-CHUNKING); I've not had a chance to evaluate
yahoodns.net yet.  Both are fine with non-pipelined QUIT and
BDAT (LAST).
