I've seen various postings about sendmail virtual domains. Basically, I have three 
DIFFERENT postings. All three say that Local Rule S98 needs to be rewritten. One
of the 3 suggests using LOCAL_RULE_0 in my *.mc file to accomplish this. OK so far.
However, the three sets of rules are not all identical:

Set 1: (from homer@light.lightlink.com)

	LOCAL_RULE_O
	R$+ < @ $+ . >		$: $1 < @ $2 > .
	R$+ < @ $+ > $*		$: $(maildomains $1@$2 $: $1 < @ $2 > $3 $)
	R$+ < @ $+ > $*		$: $(maildomains $2 $: $1 < @ $2 > $3 $)
	R$+ < @ $+ > .		$: $1 < @ $2 . >

Set 2: (from johan@josnet.se)

	Same as above, but doesn't mention using LOCAL_RULE_0

Set 3: (from chuck@bus.net)

	S98
	R$+< $+. >	$1< $2 >
	R$+< $+ >	$: < > $(usermap $1$2 $)
	R< > $+ @ $*	$: < $1 > $(usermap * @ $2 $)
	R< $+ > * $*	$: < > $1 $2
	R < $+ > 	$+ $: < > $2
	R < > $*	$: $>3 $1

Questions:

1) I assume that I want to use LOCAL_RULE_0 in my foobar.mc file, right?
2) Which set of rules is correct (or are both sets correct)?
3) One posting suggests using a dbm database, and the others suggest using
   a hashed database (makemap dbm versus makemap hash). Which do I want?

	
	
Sendmail makes my head hurt!

Thanks in advance.
