JH/19 Bug 2911: Fix a recursion in DNS lookups. Previously, if the main option
dns_again_means_nonexist included an element causing a DNS lookup which
- iteslf returned DNS_AGAIN, unbounded recursion occurred. Possible results
+ itself returned DNS_AGAIN, unbounded recursion occurred. Possible results
included (though probably not limited to) a process crash from stack
memory limit, or from excessive open files. Replace this with a paniclog
whine (as this is likely a configuration error), and returning
this resulted in behaviour of LOGIN vs. PLAIN being inconsistent under
bad coding of authenticators.
