Warning: DNS hair-puller ahead.
.... ok, having trouble sending/receiving mail from *.brooklyn.cuny.edu. (In
general, it's a very broken domain.) My SCO 506 box is the primary ns
internally, while a WinNT 4.0 PDC functions as the secondary. Works almost all
of the time. But smail cannot write to the domains above, because the primary
ns cannot resolve, say,
$ /etc/dig MX sci.brooklyn.cuny.edu
;; Querying server (# 1) address = 10.1.1.1
;; res_nsend to server default -- 10.1.1.1: Connection timed out
but if I add a nameserver directive to point to WiNT (curses!) it works.
Looking a bit ...
