You can run a check on your MX Server… there are a couple of web sites that do

One trick I use a lot when I have an infected machine on a network or a
customer with a problem is that I setup a smarthost running a milter
that runs the email through a spam checker, logs the answer and then
tempfails the emails.
Then I can analyze if there is an issue and do a silent discard by
subject or internal IP if we find a compromised machine while letting
everything else go through.
