Which variant have you used ?
[ there are three: mailertable, stickyhub, user]

What is reported by the commands below:
# which mailer is selected for listname at virtdomain before aliases
echo '3,0 listname at virtdomain' | sendmail -bt
# which flags are set for cyrus mailers
echo '=M' | sendmail -bt | grep cyrus

You can use virtusertable to redirect listname at virtdomain to listname.
Since version 8.10 virtusertable can be consulted for some non local 
email domains (domain handled by mailertable).

You can use virtusertable rewriting or you can try to debug why "cyrus 
aliases with domain" does not work [please send replies to question I 
wrote above]
