Nope Bill, sorry. As was noted in my thread, it looks to be a SASL
issue. Because some SASL plugins require a hostname, rather than IP,
SASL apparently does a reverse DNS on every connecting IP.
Maybe I'll move a request over to the SASL list to look into whether the
reverse DNS can be on a per-enabled-plugin basis (thus if I only have
enabled plugins that don't require reverse DNS, it doesn't occur). But
my personal problem with it was resolved - I kicked my ISP in the rear
and got them to fix their DNS setup. Being a local cable operator, they
actually do respond to customers' technical requests (*gasp*). :D
