List of approved 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
List of blocked 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

can define it in the GUI of the program (see chapter
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,...
Meaning of used parameters:
1) server - RBL server name
2) response - RBL server response if 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

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

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).
