It seems as though you are running cyrus version 2.1.x which is compiled
against Sasl2... Is your SendMail compiled against sasl2?? if it's
compiled against sasl1 (which I am thinking it is) then that's your
problem.. Sasl1 does not use/have saslauthd as a pwcheck method..
you need to recompile sendmail with sasl2 support.. (I'm not sure on how
to do that one,, search the mailing list, I use postfix now)

As for why netscape is ALWAYS asking for a password when sending mail..
NEtscape 4.7.x has an annoying "bug" (well I think it is).. If the smtp
server CAN support authentication then netscape WILL use it.. I've seen
no way to disable it.. If you don't want netscape to authenticate then
have your mailserver NOT broadcast that it can..
