I am not sure what is meant by something being a  third level of 
protection because each is equally important. It also appears that 
viruses anr't an issue here since I never get hits for viruses off this 
list.
On thing to note is that Spamassassin will check these lists and it will 
check ALL mail relays within a message header whereas Sendmail is 
probably only checking the connected ip.


Here is a sample of hits we get from Spamassassin's relay checks vs. the 
SMTP server doing the check.

Rule Name:      URIBL_AB_SURBL=3.812            # of occurances:        857
Rule Name:      URIBL_BLACK=3                   # of occurances:        3435

Rule Name:      URIBL_SC_SURBL=4.498            # of occurances:        2040
Rule Name:      URIBL_WS_SURBL=2.14             # of occurances:        182
Rule Name:      RCVD_IN_BL_SPAMCOP_NET=1        # of occurances:        1939
Rule Name:      RCVD_IN_DSBL=2.6                # of occurances:        222
Rule Name:      RCVD_IN_PBL=0.001               # of occurances:        2427
Rule Name:      RCVD_IN_SBL=3.16                # of occurances:        9
Rule Name:      RCVD_IN_SORBS_DUL=2.046         # of occurances:        1513
Rule Name:      RCVD_IN_SORBS_SOCKS=2.15        # of occurances:        2
Rule Name:      RCVD_IN_SORBS_WEB=1.456         # of occurances:        191
Rule Name:      RCVD_IN_XBL=3.897               # of occurances:        1043

And what postfix catches: SBL-XBL:  6735
