RBL server name
: Name of the RBL server in which the address was found
RBL reply address
: Reply address from the RBL server when spam is detected
SURBL querying is performed by looking up the name in the DNS. The DNS server to query
is the first nameserver setting in /etc/resolf.conf.
By default, this setting is disabled.
Server
Server
(spam_surbl_list)
Specifies the list of RBL servers. You can specify multiple servers, separated by commas (",").
(Initial setting: bl.spamcop.net, sbl-xbl.spamhaus.org, list.dsbl.org)
Addresses to be excluded
Skip address
Disables RBL checking for the specified addresses.
(Initial setting: 127.0.0.1 10. 192.168. 172.16.0.0/255.240.0.0)
For examples, see “
Access Control
”, 65.
If you edit the [Addresses to be excluded] setting by using the web console, the spam
rbl pass field is updated in /opt/f-secure/fsigk/conf/hosts.allow.
SURBL
SURBL
(spam_surbl)
These settings enable or disable the use of SURBLs (SPAM URL Realtime Black Lists) for
spam checking and specify the SURBL servers which are used when checking for spam.
Specify the servers separated by commas. Specify up to 199 characters.
E-mail is scanned by checking whether the domain name part of the URLs contained in the
text body or HTML body of the e-mail is registered in a SURBL server. Although the RBL
and SURBL servers are queried together, a delay of several hundred milliseconds occurs
while waiting for the server replies. If no reply is received within one second, the operation
times out and the e-mail is not identified as spam. The maximum number of queries per
e-mail is 32.
The detection name for SURBL is "FSIGK/SPAM_SURBL/(detected domain
name )[(SURBL server name):(SURBL reply address)]".
When spam is detected by checking an SURBL:
Detected domain name
: Domain name registered in the SURBL server
SURBL server name
: Name of the SURBL server in which the name was found
SURBL reply address
: Reply address from the SURBL server when spam is
detected
