Unfortunately there is not. Because it basically walks thru all the steps that an email server takes to actually send an email. Many servers will respond part way thru with that something doesn't exist etc... But if its a catchall it will pass this step. Then when it gets the mail it will either bounce at that point or go thru but be delivered to where ever it is that it gets delivered.
So those emails addresses may still receive mail, which means they are technically not invalid, but the email may just wind up going to a black hole etc...
