Log Message:
Remove dependency on mess822, the "sasl" and "tls" options, \ 
and their
respective dependencies on spamdyke and stunnel. Depend instead on
qmail-acceptutils, which provides SMTP AUTH (and new filtering
functionality) and brings its own unconditional mess822 and stunnel
dependencies. Update rc.d scripts to match.

Use CONF_FILES instead of a bunch of open-coded INSTALL cleverness.
Clean up even better with a little DEINSTALL cleverness to remove CDB
files if their source CONF_FILES are gone.

Install sensible fixsmtpio rules and viruscan signatures.

Tighten MESSAGE. The basics have gotten pretty easy. Bump version.
