Correct.

Sorry, I thought I posted the end of the story on this list:  the real
problem was getting the domains right.  Internally, if you are on
machine x.y.com, SASL stores the user "names" as name at x.  To match this,
one needs to set the realm to "x" (not x.y.com, not blank) in the exim
authenticator.  At least, that's what I got after following the Debian
cyrus/sasl advice.  The Debian exim template says the domain should be
the "short host name".  Now I know what the "short" meant.
