Look in the mail archives. This has been asked and answered recently
many times (for example: 
http://www.freebsd.org/cgi/search.cgi?words=virtual+and+mail&source=freebsd-questions&max=25&docnum=13)

Note that in addition to the advice usually given here, to modify
rulesets 40 and 98, I also had to modify my 61 ruleset to look like the
following:
S61
 
R$* < @ $* > $*         $@ $1 < @ $2 > $3               already
qualified
R$=E                    $@ $1 < @ $j>                   show exposed
names
R$+                     $: $(virtualmasqs $1 $: $1 @ $M $)
#R$+                    $: $1 < @ $M >                  user w/o host
R$+ <@>                 $: $1 < @ $j >                  in case $M
undefined
