Would having a table of these for sendmail be a good idea, and if so, how would one set up a rule to map a $1.bitnet to the corresponding internet host name from the file? Heh heh heh... Danger -- nasty mail hack approaching... Fake yourself a "bitnet" top-level domain. It should look something like (gads, I almost can't believe I'm doing this...) bitnet. in soa mthvax.cs.miami.edu. aem.mthvax.cs.miami.edu. ( 900711 ; serial 86400 ; refresh 300 ; retry 3600000 ; expire 86400 ) ; minimum bitnet. in ns mthvax.cs.miami.edu. gitvm1 in cname vm1.gatech.edu. drycas in cname drycas.club.cc.cmu.edu. ohstvma in cname ohstvma.ircc.ohio-state.edu. ohstpy in cname ohstpy.mps.ohio-state.edu. ; etc...Where DO you get a list of DNS equivalents for BITNET hosts? * in mx 0 cunyvm.cuny.edu. (Thanx to Glenn for a couple of extra sample bitnet hostnames to put in there...) Now you don't even have to notice $1.bitnet; just make sure that you pass hostnames through $[$] and they'll magically turn into The Right Thing. Now, of course, if anything outside your own nameserver ever discovers that something claims to know about a ".bitnet" top-level domain, well, there'll be hell to pay...you also take on a non-trivial task of maintaining a reasonable list of CNAMEs...I don't recommend this, but it oughta work... --karl armed and dangerous with a nameserver
