Working with RBL
–r <number_of_seconds>
– maximum allowable time for the execution of a
single filtering rule, associated with calling DNS (checking against RBL
services list, looking for a particular IP address in the DNS). The default
value is: 6.
services list, looking for a particular IP address in the DNS). The default
value is: 6.
–k <number>
– the level of detail when analyzing headers Received for
extracting IP addresses (with the consequent check of such addresses
against the RBL lists). If K = 0, then the analysis will not be performed
altogether, if K = n, then IP addresses will be extracted only from n
upper Received headers.
against the RBL lists). If K = 0, then the analysis will not be performed
altogether, if K = n, then IP addresses will be extracted only from n
upper Received headers.
Safety
–r /path/to
– mode used to work with chroot in folder /path/to.
–g user:group
, –g userid:groupid – user and group on whose behalf the
filtering process is running. It is recommended to use -g mailflt:mailflt
for all cases.
for all cases.
Working with the system log (syslog)
–V <number>
– level of system log records detail:
0
– minimum level of detail, no records made on the DoSyslog action;
1
– displaying error messages and execution of the DoSyslog action;
2
– displaying warnings;
3
and above – displaying debugging messages.
–L /path/to/logfile
– file to which messages are forwarded when the
DoSyslog action is executed.
Server load management
The parameters described below shall be altered only at very high loads
(hundreds of thousands or millions messages per day for one server).
(hundreds of thousands or millions messages per day for one server).
–m <number>
– maximum number of messages that can be processed by a
single filtering process. Once this limit is reached, the filtering process
will quit (if required, a new filtering process will be launched by the
master process). The default value is: 300.
will quit (if required, a new filtering process will be launched by the
master process). The default value is: 300.
–M <number>
– a randomization indicator for the maximum number of
messages processed by a single filtering process. The default value is:
30
30
.
The limit on the number of messages processed by each filtering
process is set as m + random number in the range from 0 to M-1; if
default values are used, each filtering process will process from 300 to
329 messages. Randomization must be used in order to avoid a
simultaneous start of a large number of filtering processes at peak loads
on the server.
