How do you avoid DNS timeouts when sending mail? At this moment, my BIND 
has many external entries cached. If I take it down, the cache is lost 
when it restarts.

I've been thinking further; presumably if there are no routes set to use 
the ppp0 interface, pppd won't dial on demand.

If you have just one set; perhaps to www.microsoft.com, then a ping to 
MS's IP address should get things moving.
