uridnssub       URIBL_SBL        zen.spamhaus.org.       A   127.0.0.2
body            URIBL_SBL        eval:check_uridnsbl('URIBL_SBL')
describe        URIBL_SBL        Contains an URL's NS IP listed in the 
SBL blocklist
tflags          URIBL_SBL        net
reuse           URIBL_SBL

    uridnsbl        URIBL_SBL_A    sbl.spamhaus.org.   A
    body            URIBL_SBL_A    eval:check_uridnsbl('URIBL_SBL_A')
    describe        URIBL_SBL_A    Contains URL's A record listed in the 
SBL blocklist
    tflags          URIBL_SBL_A    net a
  endif
endif


can the URIBL_SBL_A not use zen.spamhaus.org A 127.0.0.2

to save one more dns request ?
