Looks like it's a no go. I decided to take a quick look at the code 
(v1.80), and i was wondering if changing the query build line in 
blacklist_helo.c from

  snprintf(mysqlquery_array[fd], 512,
    "SELECT COUNT(_helo) FROM blacklist_helo WHERE _helo='%s'", 
triplet_array[fd][5]);

to

  snprintf(mysqlquery_array[fd], 512,
    "SELECT COUNT(_helo) FROM blacklist_helo WHERE '%s' LIKE _helo", 
triplet_array[fd][5]);

would cause significant performance issues.

Hugo Monteiro.
