## NAME

Mail::MtPolicyd::Plugin::DBL - mtpolicyd plugin for checking helo,sender domain,rdns against an DBL

- domain (required)

  The domain of the blacklist to query.

  Possible values: on,off

- uc\_enabled (default: empty)

  If specified the give variable within the session will overwrite the value of 'enabled' if set.

- (uc\_)sender\_mode (default: reject), (uc\_)helo\_name\_mode (default: passive), (uc\_)reverse\_client\_name\_mode (default: reject)

  Should the plugin return an reject if the check matches (reject) or just add an score (passive).

  Possible values: reject, passive

- sender\_score (default: 5)

  - helo\_name\_score (default: 1)

  <Plugin sh_dbl>
    module = "RBL"
    #enabled = "on"
    uc_enabled = "spamhaus"
    domain="dbl.spamhaus.org"
    # do not reject based on helo
    #helo_name_mode=passive
    #helo_name_score=1
    #sender_mode=reject
    #sender_score=5
    #reverse_client_name_mode=reject
