Lines in map.txt beginning with `@' match 127.0.0.1 and ::1, right?

Also, when creating a map out of a map.txt (load map.txt) in a chrooted,
network-less environment (w/o resolv.conf), cdcc-1.3.104 seems to mark
all hostnames in map.txt as invalid (or unresolvable) and doesn't retry
them even if DNS/network is available again:

	/var/dcc/map.txt:
		(...)
		dcc1.dcc-servers.net,-      RTT+1000 ms  anon
		#   undefined name or wrong IP version
		(...)

	/var/log/maillog:
		(...)
		no working DCC servers dcc1.dcc-servers.net
		dcc2.dcc-servers.net dcc3.dcc-servers.net ...
		at 127.0.0.1
		(...)


This wasn't a problem with cdcc-1.3.103.  It printed an error, but
seemed to work when DNS/network was available again:

	# cdcc -qh/var/dcc "new map; load map.txt"
	dcc1.dcc-servers.net: No address associated with hostname


I checked man cdcc but there is no such thing as `load -noresolv'.  Is
there a way to solve this without reissuing `cdcc "load map.txt"' when
DNS/network is available?
