List of the most important settings in
spamcatcher.conf
:
Parameter name
Details
approved_ip_list
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
Antispam engine parameter setup
).
blocked_ip_list
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
Antispam engine parameter setup
).
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,...
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
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_list
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_list
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 of the program (see chapter
Antispam engine parameter setup
).
dnsbl_list
List of DNSBL servers to be used in checks of domains and IP adrresses in the email body.
Format of entry is as follows:
dnsbl_list=server:response:offset,server2:response2:offset2,...
