ignored_ip_list

List of ignored IP addresses. There's no need to add the list to the spamcatcher.conf file. You can

define it in the GUI of the program (see chapter Antispam engine parameter setup ).

rbl_list

List of Realtime Blackhole servers to be used when evaluating messages. The RBL request

checks for presence of a specific IP address on a given RBL server. Subject to these checks are IP

addresses in the Received: sections in the mail header.

The entry format is as follows: rbl_list=server:response:offset,server2:response2:offset2,...

The meaning of the parameters are explained below:

1) server - RBL server name

2) response - RBL server response if the IP address was found (standard responses are 127.0.0.2,

127.0.0.3, 127.0.0.4., etc.). This parameter is optional, and if not set, all answers will be

considered.

3) offset - value from 0 to 100. Influences overall spam score. Standard value is 100, i.e. in case

of a positive check the message is assigned the spam score of 100 and is evaluated as spam.

Negative values lower the overall spam score of a message. Expect the 0 value also with

messages from senders in the approvedsenders file and the value 100 with messages from

senders in the blockedsenders file (see below).

Example 1: rbl_list=ent.adbl.org

RBL check is performed using the ent.adbl.org server. If the check is positive, the message will

be assigned a standard offset of 100 and marked as spam.

Example 2: rbl_list=ent.adbl.org::60

RBL check is performed using the ent.adbl.org server. If the check is positive, the message will

be assigned an offset of 60 which increases its overall spam score.

Example 3: rbl_list=bx9.dbl.com::85, list.dnb.org:127.0.0.4:35, req.gsender.org::-75

RBL check is performed using the defined servers (from left to right). In case of a positive check

on bx9.dbl.com the offset of 85 will be added. If the check on list.dnb.org will be positive giving a

response of 127.0.0.4 offset of 35 will be used. The offset will not be applied in cases of answers

other than 127.0.0.4. If a check is positive on req.gsender.org the spam score will be decreased

by 75 point (negative value).

rbl_max_ips

Maximum IP addresses that can be sent to RBL server check. Total number of RBL requests is

the total amount of IP addresses in the Received: sections in the email header (up to the set

limit in rbl_maxcheck_ips) multiplied by the number of RBL servers set in the rbl_list. The value

of 0 means there is no limit to the maximum number of IP addresses that can be checked.

IP addresses on the ignored_ip_list (i.e. the Ignored IP addresses list in the ESET Mail Security

settings).

This parameter is applied only if the rbl_list is enabled (i.e. contains a minimum of 1 server).

approved_domain

_list

Is a list domains and IP addresses in the email body, that are to be considered as allowed. Do

not use to whitelist emails by sender's domain!

blocked_domain_li

Is a list domains and IP addresses in the email body, that are to be considered as permanently

blocked. This is not a blacklist of sender's addresses! There's no need to add the list to the

spamcatcher.conf file. You can define it in the GUI of the program (see chapter Antispam engine

parameter setup ).

ignored_domain_li

List of domains in the email body, that are to be permanently excluded from DNSBL checks and

ignored. There's no need to add the list to the spamcatcher.conf file. You can define it in the GUI
