N.B. that the HASHBL_EMAIL initial installed -- as distributed --
SCORE is set to a lowly 1 in hashbl.cf, viz.:
loadplugin Mail::SpamAssassin::Plugin::HashBL HashBL.pm
ifplugin Mail::SpamAssassin::Plugin::HashBL
header HASHBL_EMAIL eval:check_hashbl_emails('ebl.msbl.org')
describe HASHBL_EMAIL Message contains email address found on the EBL
score HASHBL_EMAIL 1.0
endif
Highly Recommended you up it to at least 5 (ours is presently set at 9).
In the many months we’ve been using the EBL SA Plugin we have yet to
see a single FP and with the 9 SCORE we are able to blocking this type
of drop box spam at the SMTP level with SA with scores at 15 or
greater!
