You could manually check your IP address(es) here:

http://www.dnsbl.info/

Alternatively, just read your logs (or write a simple script to parse 
them for you). You'll receive a 5xx rejection and usually a reason/URL 
from the main blacklists whenever you are blocked.

If you're using postfix as your MTA, check out pflogsumm.
