You should get an "appropriate" entry in the mail logs for which "block" the 
IP was refused on if that is the case.

EG:
Jul 22 09:24:25 web4 sendmail[15970]: h6MEOKm15970: ruleset=check_relay, 
arg1=[166.68.134.174], arg2=166.68.134.174, relay=[166.68.134.174], 
reject=550 5.7.1 Mail from 166.68.134.174 refused by dnsbl.njabl.org
Jul 22 09:25:40 web4 sendmail[16045]: h6MEPdm16045: ruleset=check_relay, 
arg1=host58-49.pool21756.interbusiness.it, arg2=217.56.49.58, 
relay=host58-49.pool21756.interbusiness.it [217.56.49.58], reject=550 5.7.1 
Mail from 217.56.49.58 refused by dnsbl.njabl.org
