qmail acting funny maybe box owned


I have recently noticed that my qmail is not sending messages. I am receiving messages with no problem. I was checking /var/log/qmail/current and notcied a large number of mail that was undeliverable to a domain i do not know ( i use rcpthost file to restrict). I want to make sure spammers are not trying to get the box. Is there anyway to check to make sure it has not been compromised? Any suggestion? Thanks

well, obviously receiving messages is the easy part. I would setup an intrusion detection system such as Snort.org

Log the ip's that access the computer and see what they are actually doing.
