One tool I find useful for that type of stuff is MX toolbox http://www.mxtoolbox.com/ might be of some help, don't think it does auto notifications though.
On a side note: If your customers are getting blacklisted why not run all mail through a SMTP transparent proxy filtering out the spam? Something like ASSP http://assp.sourceforge.net/ ?Or do they control their own mail servers? If that's the case that might not work for you.
