Probably nothing - I've got the same problem running a
website with a well-known domain name. Like you, I find it
is rare to get complaints -- I think this is because the
spammers aren't fooling many people - either the recipients
deleting unwanted email without paying attention to where it
came from, or else the users are sophisticated enough to
realize that the domain name is being spoofed.

It is not a true "Joe Job" because it won't get you
blacklisted or in serious trouble unless headers are also
being spoofed or fraudulently coded to make it look like
your server is actually the source of the email.

Like you, I get email to wildcard users on my domain, but
when I have a specific nonexistent username that is being
abused in any way, I set that up as a "REJECT" in my SMTP
access database, so if anyone actually tries to reply to
that email, they'd immediately get a "no such user" bounce.

Hope this helps,

Abigail
